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
