[原创] TI bq76PL455A－Q1高可靠汽车电池监测和保护方案

TI公司的bq76PL455A-Q1是16路高可靠汽车电池监测和保护方案,集成了高速差分电容隔离通信接口,高性能14位ADC,用于温度和其它传感器的八路输入复接器,精密基准电压.本文介绍了bq76PL455A-Q1主要特性,框图,数字和模拟芯片部分功能框图,应用电路框图,以及bq76PL455EVM评估模块主要特性和电特性,电路图和材料清单.

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).
