UNISONIC TECHNOLOGIES CO., LTD UM601A LINEAR INTEGRATED CIRCUIT www.unisonic.com.tw 1 of 5 Copyright © 2017 Unisonic Technologies Co., Ltd QW-R105-028.E VOLTAGE AND CURRENT CONTROLLER DESCRIPTION The UTC UM601A integrated circuit incorporates a high stability series band gap voltage reference, two ORed operational amplifiers and a current source. This IC compares the DC volt age and the current level at the output of a switching power supply to an internal reference. It provides a feedback through an optocoupler to the PWM controller IC in the primary side. The controlled current generat or can be used to modify the level of current limitation by o ffsetting the information coming from the current sensing resistor. It can be used in voltage supervisors, every types of application requiring a precision voltage regulation and current limitation, over voltage protection, battery charger with a constant voltage and a limited output current. DIP-8 SOP-8 FEATURES * 1.24V Series Voltage Reference with 10mA Output Current and 1% Precision (UM601A ) * Two Operational Amplifiers with ORed Output and 1MHz Gain Bandwidth Product * Built-In Current Generator with Enable / Disable Function * 4.5 ~ 32V Supply Voltage Range ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing UM601AL-D08-T UM601AG-D08-T DIP-8 Tube UM601AL-S08-R UM601AG-S08-R SOP-8 Tape Reel UM601AG-D08-T (1) Packing Type (2) Package Type (3) Green Package (1) T: Tube, R: Tape Reel (2) D08: DIP-8, S08: SOP-8 (3) G: Halogen Free and Lead Free, L: Lead Free MARKING DIP-8 SOP-8 UTC UM601A 2 3 41 5678 Date Code L: Lead Free G: Halogen Free Lot Code

PIN DESCRIPTION PIN NAME TYPE FUNCTION 1. V REF OUTPUT Voltage Reference Output 1. 24V, 10mA max. Do not short circuit 2. C SEN INPUT Current source enable input. This current source can be used to offset the voltage measurement on the sense resist or and therefore to modify the charge current. The current source is enabled w hen the input volage on pin 2 is lower than 0.8V 3. C RREF INPUT Current Limitation Reference Input 4. GND INPUT Ground 5. C RIN INPUT Current Limitation Loop Input, connected to the sense resistor 6. OUTPUT OUTPUT Output pin common to the voltage regulat ion and current limitation loops. This output can drive the primary side (LED) of an optocoupler 7. V RIN INPUT Voltage Regulation Loop Input 8. V CC INPUT Power Supply Input (4.5 ~ 32VDC)
