UU6043B

UNISONIC TECHNOLOGIES CO., LTD UU6043B LINEAR INTEGRATED CIRCUIT FLASHER IC WITH 18mΩ SHUNT  DESCRIPTION The UTC UU6043B is a miconductor integrated circuit designed for relay-controlled automotive flashers where a high level EMC is required. Lamp outage is indicated by frequency doubling during hazard warning as well as direction mode.  FEATURES * Temperature and supply voltage compensated frequency * Warning indication of lamp failure by means of frequency doubling * Relay driver output with high current carrying capacity and low saturation output * Minimum lamp load for flasher operation: ≥ 1 W * Very low susceptibility to EMI  ORDERING INFORMATION Ordering Number Lead Free Halogen Free UU6043BL-D08-T UU6043BG-D08-T UU6043BL-S08-R UU6043BG-S08-R Package DIP-8 SOP-8 DIP-8 SOP-8 Packing Tube Tape Reel  MARKING DIP-8 SOP-8 www.unisonic.com.tw Copyright © 2017 Unisonic Technologies Co., Ltd 1 of 5 QW-R121-024.E UU6043B  PIN CONFIGURATION GND 1 VS 2 REL 3 OSC 4 LINEAR INTEGRATED CIRCUIT 8 SI 7 LD 6 VS 5 OSC  PIN DESCRIPTION PIN NO. 1 2 3 4 5 6 7 8 PIN NAME GND VS REL OSC OSC VS LD SI IC ground Supply voltage Relay driver C1 Oscillator R1 Oscillator Supply voltage, Sense Lamp outage detection Start input (49a)  BLOCK DIAGRAM DESCRIPTION VS VS 62 OSC 4 Pulse generator OSC 5 V6-49 mV 20kΩ K1 K2 20kΩ K3 20kΩ 5kΩ 7 LD 3 REL 23V 5kΩ IC Ground 8 SI 1 GND UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 2 of 5 QW-R121-024.E UU6043B LIN...
