DOUBLE CONSTANT VOLTAGE CONTROLLERS

DESCRIPTION

The UTC UM611 is a highly integrated solution for double

constant voltage application.

The UTC UM611 contains two voltage reference (0.6V and

0.8V) and two operational amplifiers. The 0.8V voltage reference,

combined with one operational amplifier, makes of an ideal

voltage controller for use in adapters and battery chargers. The

0.6 voltage reference, combined with another operational

amplifier, makes of an ideal current limiter for use in adapters and

battery chargers.
