[原创] TI bq76PL536A－Q1电动汽车锂电池监视和保护参考设计

TI公司的bq76PL536A-Q1是可堆栈的三--六颗锂电池组保护器和模拟前端(AFE),集成了精密的ADC,单独的电池电压和温度保护,电池平衡和给用户电路供电的精密V稳压器.电源电压从7.2 V 到 27 V,主要用在电动和混合动力汽车,电动自行车和电动滑板车,不间断电源(UPS)和大型电池系统.本文介绍了bq76PL536A-Q1主要特性,框图和简化的系统连接图以及锂电池监视和保护参考设计TIDA-00821主要特性,框图,电路图,材料清单和PCB设计图.

The bq76PL536A-Q1 is a stackable three to six series cell lithium-ion battery pack protector and analog front end (AFE) that incorporates a precision analog-to-digital converter (ADC); independent cell voltage and temperature protection; cell balancing, and a precision 5-V regulator to power user circuitry.

The bq76PL536A-Q1 integrates a voltage translation and precision analog-to-digital converter system to measure battery cell voltages with high accuracy and speed.

The bq76PL536A-Q1 provides full protection (secondary protection) for overvoltage, undervoltage, and overtemperature conditions. When safety thresholds are exceeded, the bq76PL536A-Q1 sets the FAULT output. No external components are needed to configure or enable the protection features.
