[原创] ST TBC03锂电池充电器解决方案

ST公司的TBC03是具有低静态电流的LDO稳压器和负载开关的锂电池充电器,包括150mA LDO,2个SPDT负载开关,以及保护电路模块(PCM),采用CC/CV算法进行充电电池,快速充电电流高达650mA,预充电电流从1mA起,可调浮电压高达4.45V,主要用在智能手表和可穿戴设备,健身和医疗设备,以及锂电池和其它Li-Poly电池可再充电设备.本文介绍了TBC03主要特性,框图,应用电路图及其材料清单,Li-Ion/Li-Po电池电源管理评估板STEVAL-ISB035V1主要特性,电路图,材料清单和PCB设计图.

The STBC03 is a highly integrated power management, embedding a linear batterycharger, a 150 mA LDO, 2 SPDT load switches, and a protection circuit module(PCM) to prevent the battery from being damaged under fault conditions.

The STBC03 uses a CC/CV algorithm to charge the battery; the fast charge and the pre-charge current can be both independently programmed using dedicatedresistors. The termination current is set to 5% of the programmed fast charge current,but has fixed values for fast charge currents lower than 20 mA. The battery floatingvoltage value is programmable and can be set to a value up to 4.45 V.
