U2400B
Charging of Batteries with Automatic Pre-Discharge
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
D Three time selections:
0.5 h, 1 h or 12 h with subsequent trickle charge
operation
D Battery temperature and contact monitoring
D Charging interrupt for overvoltage or excessive
temperature
D Automatic pre-discharge possible
D Separate charge- and discharge outputs
D Pulse-width modulation facility of charge- and
discharge current for matching to transformer or
battery data
D Timer clock via mains or internal oscillator
D Reference voltage source
D LED-status output for mode indication
Case: DIP16, SO16L
