UNISONIC TECHNOLOGIES CO., LTD UC34363 Preliminary LINEAR INTEGRATED CIRCUIT CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER FOR BATTERY CHARGERS DESCRIPTION The UTC UC34363 is a switch controller for constant voltage, constant current (CV/CC) application. The device could be used for battery charge. UTC UC34363 is used of SOP-8 packages. Additionally the UTC UC34363 intergrated a internal compensation capacitor, so that the application is simplicial. FEATURES * CV/CC linear charge * 3A maximum charge current * PWM control Mode * Available charge current * Over Voltage protect ,Over Current Protect * Enable Control function * Very Low Power Dissipation in Standby Mode ORDERING INFORMATION Ordering Number Lead Free UC34363L-S08-R Halogen Free UC34363G-S08-R Package Packing SOP-8 Tape Reel UC34363L-S08-R (1)Packing Type (1) R: Tape Reel (2)Package Type (2) S08: SOP-8 (3)Lead Free (3) L: Lead Free, G: Halogen Free MARKING INFORMATION PACKAGE MARKING SOP-8 www.unisonic.com.tw Copyright © 2014 Unisonic Technologies Co., Ltd 1 of 4 QW-R103-059.b UC34363 Preliminary PIN CONFIGURATION PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME VCC CVENABLE VREF CC+ CCOUTPUT GND LINEAR INTEGRATED CIRCUIT DESCRIPTION Power Supply Negative Input of the Voltage Amplifier Enable Controlled ON/OFF for IC 3V external Voltage Reference Positive Input of Current Amplifier Negative Input of Current Amplifier Output Ground BLOCK DIAGRAM VCC GND + + - S OCP CV- R Driver Output Q Clock S Q Delay R Ramp COMP + EN D1 + - D2 CV CC + Compensation VREF CC- - VREF=3V UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw Compensation CC+ 2 of 4 QW-R103-059.b UC34363 Preliminary LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATING PARAMETER SYMBOL RATINGS UNIT Power Supply Voltage VCC 30 V CC+ Voltage VCC+ 10 V CC- Voltage VCC10 V CV- Voltage VCV10 V Operating Junction Temperature TJ 125 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
