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.
