U6432B - Low-power Flasher IC with 18-mOMShunt

Datasheet Summary

Description

The U6432B is an advanced automotive flasher IC which provides low standby current.

Its basic function is equal to Atmel’s flasher IC U6043B but low current consumption and frequency doubling disabling make outstanding differences.

AUTO

Features

  • Temperature and Voltage Compensated Frequency.
  • Warning Indication of Lamp Failure by Means of Frequency Doubling only in Direction.
  • Mode Voltage Dependence of the Car Indicator Lamps also Compensated for Lamp Failure Relay Output with High Current-carrying Capacity and Low Saturation Voltage Load-dump Protection Minimum Lamp Load for Flasher Operation ³ 1 W Low Susceptibility to EMI Extremely Low Standby Curr.
