UU4793

UNISONIC TECHNOLOGIES CO., LTD UU4793 Preliminary LINEAR INTEGRATED CIRCUIT OVERLOAD MONITORING WITH RESISTIVE LOAD, VT = 44.5 mV  DESCRIPTION The UTC UU4793 is a bipolar integrated circuit designed for monitoring over loading or short circuit in automotive or industrial applications. The threshold VT is 44.5 mV and V4, 6=VS-VT. VT is not dependent of the power supply voltage VS. If the voltage developed across shunt resistor RSH exceeds VT, IC turns on the output, or else turns off the output. The output is turned off when input switch Pin 8 is open or there is a lack of power supply voltage. The output breakdown voltage is decided by the Z-diodes Z3 and Z5 which have a typical value of VZ = 22 V. A not used of the comparator input have to be connected to Pin 7.  FEATURES * Two common reference comparators * Tight threshold tolerance * Constant threshold * Output with NPN * 8 kV - ESD protection * Protection of reverse polarity * Load-dump protection  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UU4793L-S08-R UU4793G-S08-R Package SOP-8 Packing Tape Reel  MARKING www.unisonic.com.tw Copyright © 2017 Unisonic Technologies Co., Ltd 1 of 5 QW-R121-022.b UU4793  PIN CONFIGURATION Preliminary LINEAR INTEGRATED CIRCUIT  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME GND VS OUT2 IN1 OUT1 IN2 VREF Input Switch Ground Power supply voltage Comparator 2 output Comparator 1 input Comparator 1 output Comparator 2 input Reference voltage Inp...
