Auto Flasher ASIC

Product Image (U2043B)

U2043B Automotive Direction Indicator IC

Price: 0.28 USD ($)/Piece

U2043B was designed for use in conjunction with a relay in automotive applications. It is also applicable for other warning lamps such as “handbrake ON,” etc.

MC 33193Automotive LED Direction Indicator IC

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 23mΩ shunt resistor. The LD33193 has a standby mode of operation requiring very low standby supply current and can be directly connected to the vehicle’s 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 (23mΩ) to be used. It can be used for LED lamp flasher. And the relay can be replaced with a transistor to achieve non-contact.

Product Image (U2043C)

U2043C Automotive Direction Indicator flahser IC

The bipolar integrated circuit U2043C is used in 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.

Product Image (UAA1041B)

UAA1041B Automotive Direction Indicator Flahser IC

LD1041 (analog UAA1041B) was designed for use in conjunction with a relay in automotive applications. It is also applicable for other warning lamps such as “handbrake ON,” etc.

Product Image (LT4761)

LT4761 Automotive Direction Indicator Flasher IC

Description The bipolar integrated circuit LT4761 is used in 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.

Product Image (U2044B)

U2044B Dual Output Flasher IC

The integrated circuit L2044G (analog U2044B) is used in relay controlled automotive flashers. With two output stages each side of the vehicle is controlled separately. A left and a right direction indicator input with only a small control current makes switch contacts for small loads possible. The separate hazard warning input simplifies the construction of the hazard switch. Lamp outage is indicated by frequency doubling during direction mode. Thanks to the extreme low current consumption L2044G can be connected to the battery directly. The IC can used for 24V circuit and control LED.
