The SENASIC SNP736 is a highly integrated Tire Pressure Monitoring System (TPMS) integrated circuit designed for modern automotive, electric vehicle, and intelligent mobility applications. It combines a high-precision pressure sensor, temperature sensor, MEMS accelerometer, battery voltage monitoring, RF transmitter, and an embedded 8051 microcontroller in a compact LGA24 package (6.0 × 5.0 × 1.9 mm).
The device supports Bluetooth Low Energy (BLE) 4.2 as well as Sub-1GHz RF communication (315/433MHz and 2.4GHz), making it suitable for both traditional TPMS architectures and next-generation connected vehicle platforms. It delivers calibrated pressure measurement with ±3 kPa accuracy over a -40°C to +125°C operating range, supporting pressure ranges of 900 kPa or 1900 kPa depending on the selected version.
The integrated temperature sensor provides ±2°C accuracy between -20°C and +70°C for precise pressure compensation, while the built-in MEMS accelerometer enables intelligent motion detection to optimize measurement intervals and extend battery life. Operating from a 2.1-3.6V supply, the SNP736 significantly reduces PCB complexity and manufacturing costs for automotive OEMs and Tier-1 suppliers developing TPMS modules for passenger cars, commercial vehicles, and electric motorcycles.
