TI公司的bq76PL455A-Q1是用于高可靠汽车应用的16路锂电池监测和保护器件.集成的高速差分电容隔离通信接口允许16个bq76PL455A-Q1通过UART接口和主器件通信,监测和检测几种不同的故障状态包括过压,欠压,超温和通信故障.满足 AEC-Q100汽车规范,主要用在电动和混合动力汽车(EV, HEV,PHEV, Mild Hybrid),48V系统,能量存储(ESS)和UPS以及电动自行车和电动滑板车.本文介绍了bq76PL455A-Q1主要特性,框图,应用电路以及16路锂电池平衡参考设计TIDA-00817主要特性,框图,电路图,材料清单和PCB设计图.

The bq76PL455A-Q1 device is an integrated 16-cellbattery monitoring and protection device, designed forhigh-reliability automotive applications. The integratedhigh-speed, differential, capacitor-isolatedcommunications interface allows up to sixteenbq76PL455A-Q1 devices to communicate with a hostvia a single high-speed Universal AsynchronousReceiver/Transmitter (UART) interface.

The bq76PL455A-Q1 monitors and detects severaldifferent fault conditions, including:overvoltage,undervoltage,overtemperature,and communicationfaults. Six GPIO ports as well as eight analog AUXADC inputs are included for additional monitoring and programmable functionality.A secondary thermalshutdown is included for further protection.

bq76PL455A-Q1主要特性:

• Monitors and Balances 6-to-16 Cells per Device
• Highly Accurate Monitoring..
