描述 Description

The monolithic integrated circuit, U2400B, is a bipolar circuit, designed for automatic recharging of NiCd/NiMH batteries. It has controlled and defined charging characteristics for various charging sequences with subsequent trickle charge operation. The long life
Memory Effect
of the recharging cell remains intact.
