SNP805 Battery pressure sensor IC is the first domestic battery pack pressure sensor monitoring IC, which is designed specifically for the pressure monitoring application of new energy vehicle battery packs.The product consists of 8-bit MCU, 12-bit ADC, temperature sensor, pressure sensor and supply voltage monitoring unit. 

Core features

High-precision pressure measurement: The pressure accuracy is ±1.2kPa@25°C (absolute pressure), the pressure measurement resolution is 0.1kPa/LSB, and the pressure measurement range is 40kPa-260kPa.

High integration: It integrates an 8-bit MCU, a 12-bit ADC, a temperature sensor, a pressure sensor, and a power supply voltage monitoring unit.

Low power consumption: The typical current in monitoring mode is less than 30µA.

Wide temperature range: The operating temperature range is -40°C-125°C.

Diverse interfaces: It supports SPI, UART, and PWM interfaces, which is convenient for communication with the host system.

Built-in alarm function: It can measure the pressure change of the battery pack in real time, and provide an alarm signal when the pressure change exceeds the normal range.

Package form: Adopt LGA 24 package, with dimensions of 6.0mm x 5.0mm x 1.9mm.

Application field: It has been successfully applied to the battery pack systems of many well-known automobile brands, and plays an indispensable role in the battery safety protection of new energy vehicles.
