U643B Product details

Description

The bipolar integrated circuit U643B 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.

Features

• Temperature and Supply Voltage Compensated Flashing Frequency

• Frequency Doubling Indicates Lamp Outage

• Relay Driver Output with High Current Carrying Capacity and Low Saturation Voltage

• Minimum Lamp Load for Flasher Operation: ≥ 1W

• Very Low Susceptibility to EMI

• Protection According to ISO/TR 7637/1 Level 4
