Introduction

AI Translation

The bq76PL455A-Q1 device is an integrated 16-cell battery monitoring and protection device, designed for high-reliability automotive applications. The integrated high-speed, differential, capacitor-isolated communications interface allows up to sixteen bq76PL455A-Q1 devices to communicate with a host via a single high-speed Universal Asynchronous Receiver/Transmitter (UART) interface. The bq76PL455A-Q1 monitors and detects several different fault conditions, including: overvoltage, undervoltage, overtemperature, and communication faults. Six GPIO ports as well as eight analog AUX ADC inputs are included for additional monitoring and programmable functionality. A secondary thermal shutdown is included for further protection. AEC-Q100 Qualified With the Following Results: Device Temperature Grade 2: -40°C to 105°C Ambient Operating Temperature Range Device HBM ESD Classification Level 2 Device CDM ESD Classification Level C3
