L2044 Datasheet | Unisonic Technologies

DESCRIPTION The UTC L2044 is a dual output stages flasher designed as a relay driver for flashing light control in automotive applications. Both sides direction indicator input with only a small control current makes switch contacts for small loads possible. Each side of the vehicle is controlled separately. The construction of the hazard switch could be simplified due to hazard warning input is separate. The flasher will dramatically increase the flash frequency by a typical ratio of 2:1 if lamp fault is detected. The UTC L2044 can be directly connected to the battery due to extreme low current consumption. - FEATURES - Temperature and Supply Voltage pensated Flashing Frequency - Frequency Doubling Indicates Lamp Fault. - Two Relay Driver Outputs with High Current-carrying Capacity and Low Saturation Voltage - Minimum Lamp Load for Flasher Operation: ≥ 1W - Very Low Sensitivity to EMI - Extremely Low Current Consumption<10μA ( at Switches Open) - Reverse Polarity Protection - Three Control Inputs: Left, Right and Hazard Warning - ORDERING INFORMATION Ordering Number Lead Free Halogen Free L2044L-D14-T L2044G-D14-T - L2044G-S14-R Package DIP-14 SOP-14 Packing Tube Tape Reel - MARKING DIP-14 SOP-14 .unisonic..tw Copyright © 2015 Unisonic Technologies Co., Ltd 1 of 5 QW-R121-001.C - PIN CONFIGURATION LINEAR INTEGRATED CIRCUIT - PIN DESCRIPTION PIN No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 PIN NAME OSC SIL SIR SIHW VCC CR1 CR2 LD VCC GND OR1 VS OR2 OSC FUNCTION Oscillator Start input left Start input right Start input hazard warning VCC Control input relay 1 Control input relay 2 Lamp failure detection VCC ground Output relay 1 VCC Output relay 2 Oscillator UNISONIC TECHNOLOGIES CO., LTD .unisonic..tw 2 of 5 QW-R121-001.C - BLOCK...
