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.

Features
● Three time selections: 0.5 h, 1 h or 12 h with subsequent trickle charge operation
● Battery temperature and contact monitoring
● Charging interrupt for overvoltage or excessive temperature
● Automatic pre-discharge possible
● Separate charge- and discharge outputs
● Pulse-width modulation facility of charge- and discharge current for matching to transformer or battery data
● Timer clock via mains or internal oscillator
● Reference voltage source
● LED-status output for mode indication
