Overview
UNISONIC TECHNOLOGIES CO.
, LTD UM611 Preliminary LINEAR INTEGRATED CIRCUIT 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.
 FEATURES * Constant voltage control * Low supply current: 0.
45mA (VCC=5V) * Easy compensation * Precision Internal Voltage Reference: 0.
6V/0.
8V * Low external component * Operating power supply : 3V~20V  APPLICATION * battery chargers * DCDC application * ACDC adapters  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UM611L-S16-R UM611G-S16-R 54 6 23 1 SOT-26 Package SOT-26 Packing Tape Reel  MARKING 654 M611 L: Lead Free G: Halogen Free 123 www.
