摘要
LT8705A是一款四路开关降压-升压直流/直流控制器,可在高于、低于或等于输出电压的输入电压下工作。文章介绍了基于LT8705A的充电电路的主要硬件电路的设计以及如何通过外部MCU和数字电位器对充电参数进行配置,从而实现对不同电压、不同容量的锂电池组进行充电的功能。
The LT8705A is a Synchronous 4-Switch Buck-Boost DC/DC Controller that operates at input voltages above,below,or equal to the output voltage.This article introduces the design of the main hardware circuit of the LT8705A based charging circuit and how to configure the charging parameters through the external MCU and digital potentiometer,so as to realize the function of charging the lithium battery with different voltages and different capacities.
