Mc 33193automotive Led Direction Indicator Ic

Description

The LD33193 is a new generation industry standard Flasher ASIC. It has been developed for enhanced EMI sensitivity, system reliability, and improved wiring simplification. The LD33193 is without lamp short circuit detection and using a 23m shunt resistor. The LD33193 has a standby mode of operation requiring very low standby supply current and can be directly connected to the vehicles battery. It includes an RF filter on the fault detection pin (Pin 7) for EMI purposes. Fault detection thresholds are reduced relative to those of the Flasher IC, allowing a lower shunt resistance value (23m) to be used. It can be used for LED lamp flasher. And the relay can be replaced with a transistor to achieve non-contact.
