Internal structure of UC3906

Relevant key device information applied in this article: UC3906 UC3906 is a dedicated chip for charging valve-controlled sealed lead-acid batteries. It integrates three charging logic control and detection functions required to achieve optimal charging of valve-controlled sealed lead-acid batteries, and It has the functions of ambient temperature self-adaptation, charge and discharge level self-adaptation, current limiting and under-voltage protection. The temperature compensation technology used can make various charging conversion voltages change with the change of the voltage temperature coefficient of the valve-regulated sealed lead-acid battery, so that the valve-regulated sealed lead-acid battery can achieve the optimal charging state within a wide temperature range. Its internal structure diagram is shown below
