产品说明

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.

The bq76PL455A-Q1 has features that customers may find useful to help them meet functional safety standard requirements (for example, ISO26262). See Safety Manual for bq76PL455A-Q1 (SLUUB67).
