Texas Instruments BQ76PL455APFCR

Description
The bq76PL455A is an integrated 16-cell battery monitoring and protection device designed for high-reliability, high-voltage industrial applications. It features a high-speed, differential, capacitor-isolated communications interface that allows up to 16 devices to communicate with a host through a single UART interface. The bq76PL455A monitors and detects various fault conditions, including overvoltage, undervoltage, overtemperature, and communication faults. It also includes six GPIO ports and eight analog AUX ADC inputs for additional monitoring and programmable functionality. A secondary thermal shutdown is included for further protection.

Features
Monitors and balances 6 to 16 cells per device
Highly accurate monitoring with a 14-bit ADC and internal reference
Eight AUX inputs for temperature and other sensors with an input voltage range of 0 V to 5 V
Integrated precision reference
Integrated protector with separate Vref for overvoltage (OV) and undervoltage (UV) comparators and programmable VCELL set points
Engineered for high system robustness with a stackable isolated differential UART up to 1 Mb/s, daisy-chainable with twisted pair, and passes bulk current injection (BCI) test
Designed for robust hot-plug performance
Passive balancing with external n-FETs and active balancing with EMB1428Q/EMB1499Q
