This device can drive relays, LEDs, or resistive loads up to 16 V. The ULN2003V12 supports 3.3-V to 5-V CMOS logic input interface, thus making it compatible to a wide range of microcontrollers and other logic interfaces. The ULN2003V12 features an improved input interface that minimizes the input DC current drawn from the external drivers. The ULN2003V12 features an input RC snubber that greatly improves its performance in noisy operating conditions. The ULN2003V12 channel inputs feature an internal input pulldown resistor, thus allowing input logic to be tri-stated. The ULN2003V12 may also support other logic input levels (for example, TTL and 1.8 V). 7.2 Functional Diagram IN1 1 16 OUT1 IN2 2 15 OUT2 IN3 3 14 OUT3 IN4 4 13 OUT4 IN5 5 12 OUT5 IN6 6 11 OUT6 IN7 7 10 OUT7 GND 8 9 COM Copyright (c) 2016, Texas Instruments Incorporated 7.3 Feature Description As shown in Figure 3, each output of the ULN2003V12 features an internal free-wheeling diode connected in a common-cathode configuration at the COM pin. The ULN2003V12 provides flexibility of increasing current sink capability through combining several adjacent channels in parallel.

However, ULN2003V12 input interface may support other logic input levels as well. See Figure 1 and Figure 2 to establish VOL and the corresponding typical load current levels for various input voltage ranges. See Applications and Implementation for an implementation to drive 1.8-V relays using ULN2003V12. 7.3.2 Input RC Snubber ULN2003V12 features an input RC snubber that helps prevent spurious switching in noisy environment. Connect an external 1-k to 5-k resistor in series with the input to further enhance ULN2003V12's noise tolerance. 7.3.3 High-impedance Input Drivers ULN2003V12 features a 300-k input pulldown resistor. The presence of this resistor allows the input drivers to be tri-stated. When a high-impedance driver is connected to a channel input the ULN2003V12 detects the channel input as a low level input and remains in the OFF position. The input RC snubber helps improve noise tolerance when input drivers are in the high-impedance state. 7.4 Device Functional Modes Table 1 lists the functional modes for this device. Table 1.

TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information Peripheral drivers such as the ULN2003V12 are primarily used in the following applications: * Stepper Motor Driving * Relay and Solenoid Driving * LED Driving * Logic Level Shifting Peripheral Drivers are not limited to one specific application at a time, but can be used for all of these applications simultaneously. For example, one device could enable driving one stepper motor, driving one relay, driving an LED, and shifting a 3.3-V logic signal to a 12-V logic signal at the same time. 8.2 Typical Applications 8.2.1 Unipolar Stepper Motor Driver The Figure 4 shows an implementation of ULN2003V12 for driving a unipolar stepper motor.

When an input pin is left open, the internal 300k pulldown resistor pulls the respective input pin to GND potential. For higher noise immunity use an external short across an unconnected input and GND pins. See Stepper Motor Driving with Peripheral Drivers (SLVA767) for additional information regarding stepper motor driving. 8.2.1.2 Application Curves Figure 5. Freewheeling Diode VF vs IF 8.2.2 Inverting Logic Level Shifter To use ULN2003V12 as an open-drain inverting logic level shifter, configure the device as shown in Figure 6. The device input and output logic levels can also be set independently. When using different channel input and output logic voltages, connect the ULN2003V12 COM pin to the maximum voltage.

Because the device pulls the output transistor low when input is high, this configuration is useful for applications requiring inverting logic with the level shifting operation. 8.2.2.2 Detailed Design Procedure To operate in level shifting operation, timing and propagation delay must be kept in mind. Depending on the pullup resistors at the output ULN2003V12 exhibits different propagation delays. The choice of pullup resistor is dependent on the drive required at the output. The device can pull output to ground with the output transistor, but to transition from low to high output resistor plays a critical role. If high drive at output is required, use Equation 1 to calculate a lower resistance. RPullup = OUT1_VSUP / IDrive (1) For example, a drive of 5 mA is required at the output for 1.8-V to 5-V translation application. RPullup = OUT1_VSUP / IDrive = 5 / 0.005 =1k (2) 8.2.3 Maximum Supply Selector The Figure 7 implements a maximum supply selector along with a 4-channel logic level shifter using a single ULN20003V12.

The maximum supply is then used as a pullup voltage for level shifters. Limit the net GND pin current to less than 100-mA DC to ensure reliability of the conducting diode. The unconnected inputs IN5 to IN7 are pulled to GND potential through 300-k internal pulldown resistor. 10 Submit Documentation Feedback Copyright (c) 2012-2016, Texas Instruments Incorporated Product Folder Links: ULN2003V12 ULN2003V12 www.ti.com SLRS060C - MAY 2012 - REVISED NOVEMBER 2016 Typical Applications (continued) 8.2.4 Constant Current LED Driver When configured as per Figure 8, the ULN2003V12 outputs OUT1 to OUT6 act as independent constant current sources.

Although not required, TI recommends putting a bypass capacitor of 0.1 F across the COM pin and GND pin. 10 Layout 10.1 Layout Guidelines Thin traces can be used on the input due to the low current logic that is typically used to drive ULN2003V12. Take care to separate the input channels as much as possible, as to eliminate cross-talk. TI recommends thick traces for the output to drive high currents that may be required. Wire thickness can be determined by the trace material's current density and desired drive current. Because all of the channels currents return to a common ground, it is best to size that trace width to be very wide. Some applications require up to 1 A. 10.2 Layout Example IN1 OUT1 IN2 OUT2 IN3 OUT3 IN4 OUT4 IN5 OUT5 IN6 OUT6 IN7 OUT7 GND COM 0.1 F 10.3 Thermal Considerations 10.3.1 On-chip Power Dissipation Use Equation 3 to calculate ULN2003V12 on-chip power dissipation PD. N PD = a VOLi ILi i=1 where * * N is the number of channels active together VOLi is the OUTi pin voltage for the load current ILi (3) 10.3.2 Thermal Reliability TI recommends limiting the ULN2003V12 IC's die junction temperature to less than 125C. The IC junction temperature is directly proportional to the on-chip power dissipation. Use Equation 4 to calculate the maximum allowable on-chip power dissipation for a target IC junction temperature. PD(MAX) = (T J(MAX) - TA ) qJA where * * * TJ(MAX) is the target maximum junction temperature TA is the operating ambient temperature JA is the package junction to ambient thermal resistance (4) Submit Documentation Feedback Copyright (c) 2012-2016, Texas Instruments Incorporated Product Folder Links: ULN2003V12 13 ULN2003V12 SLRS060C - MAY 2012 - REVISED NOVEMBER 2016 www.ti.com 11 Device and Documentation Support 11.1 Documentation Support For related documentation see the following: Stepper Motor Driving with Peripheral Drivers (SLVA767) 11.2 Receiving Notification of Documentation Updates To receive notification of documentation updates, navigate to the device product folder on ti.com.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
