Texas Instruments  BQ76PL455APFCR

The bq76PL455A device is an integrated 16-cell battery monitoring and protection device, designed for high-reliability, high-voltage industrial applications. The integrated high-speed, differential, capacitor-isolated communications interface allows up to sixteen bq76PL455A devices to communicate with a host through a single high-speed Universal Asynchronous Receiver/Transmitter (UART) interface.

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