FXPS7550A4 Analog absolute pressure sensor, 20 to 550 kPa Rev. 4.1 -- 29 May 2019 1 Product data sheet General description The FXPS7550A4 high-performance, high-precision absolute pressure sensor consists of a compact capacitive micro-electro-mechanical systems (MEMS) device coupled with a digital integrated circuit (IC) producing a fully calibrated analog output. This sensor is ideal for many automotive applications such as manifold air pressure (MAP), turbo MAP, comfort seating and other applications requiring operating absolute pressure ranges up to 550 kPa. The sensing element is based on NXP's high precision capacitive pressure cell technology. The architecture benefits from redundant pressure transducers as an expanded quality measure. It delivers highly accurate ratiometric analog readings of absolute pressure while operating from either a 3.3 V or 5.0 V power supply. The sensor operates over a pressure range of 20 kPa to 550 kPa and over a wide temperature range of -40 C to 130 C The sensor comes in an industry-leading 4 mm x 4 mm x 1.98 mm, restriction of hazardous substances (RoHS) compliant, high-power quad flat no-lead (HQFN) [1] [2] package suitable for small printed circuit board (PCB) integration. Its AEC-Q100 compliance, high accuracy, reliable performance and high media resistivity make it ideal for use in automotive, industrial, and consumer applications. 2 Features and benefits * * * * * * * * 3 Absolute pressure range: 20 to 550 kPa Operating temperature range: -40 C to 130 C Analog output for monitoring of the absolute pressure signal Pressure transducer and digital signal processor (DSP) - Internal self test Capacitance to voltage converter with anti-aliasing filter Sigma delta ADC plus sinc filter 800 Hz or 1000 Hz low-pass filter for absolute pressure Lead-free, 16-pin HQFN, 4 mm x 4 mm x 1.98 mm package Applications 3.1 Automotive * Manifold air pressure - MAP, TurboMAP * Small engine control * Liquid propane gas (LPG) or compressed natural gas (CNG) engine management FXPS7550A4 NXP Semiconductors Analog absolute pressure sensor, 20 to 550 kPa 3.2 Industrial * * * * Compressed air Manufacturing line control Gas metering Weather stations 3.3 Medical/Consumer * Blood pressure monitor * Medicine dispensing systems * White goods 4 Ordering information Table 1.Ordering information Type number FXPS7550A4 Package Name Description Version HQFN16 HQFN16, plastic, thermal enhanced quad flat pack; no leads; 16 terminals; 0.8 mm pitch; 4 mm x 4 mm x 1.98 mm body SOT1573-1 4.1 Ordering options Table 2.Ordering options FXPS7550A4 Product data sheet Device Range (kPa) Packing FXPS7550A4T1 20 to 550 kPa Packing Tape and Reel All information provided in this document is subject to legal disclaimers.

The analog output is enabled by default. Selecting the analog output enables the following functions: * The non-interpolated PABS sensor data output is saturated to 10 bits and converted to an unsigned value. * The 10-bit sensor value is input into a summer clocked at 10 MHz. * The carry from the summer circuit generates a PCM output. * The PCM signal is filtered by a 2-pole active low pass filter to generate an analog signal.

Absolute maximum ratings are stress ratings only; functional operation at these ratings is not guaranteed. Exposure to absolute maximum ratings conditions for extended periods might affect device reliability. This device contains circuitry to protect against damage due to high static voltage or electrical fields. NXP advises that normal precautions be taken to avoid application of any voltages higher than maximum-rated voltages to this high-impedance circuit.

Highly pressurized gas molecules may permeate through the gel and then occupy boundaries between material surfaces within the sensor package. When decompression occurs, the gas molecules may collect, form bubbles and possibly result in delamination of the gel from the material it protects. If a bubble is located on the pressure transducer surface or on the bond wires, the sensor measurement may shift from its calibrated transfer function.
