    Products Detail

    The U641B is a cost-effective solution for accurate timing control in automotive wiper systems. It provides intermittent and wipe/wash operations with priority given to wipe/wash mode. The interval pause (4 to 20 s) and after-wiping time (2 to 20 s) can be set using external resistors. The device requires a park switch signal for proper operation and features a relay driver with Z-diode, interference protection, and load-dump protection. All timing sequences are determined by a single external capacitor.

    Key Features

    • Interval Pause: 4-20 s
    • After-wiping Time: 2-20 s
    • Wiper Motor Park Switch
    • Prewash Delay: 0.6 s
    • Wipe/Wash Mode Priority
    • Single External Capacitor for Timing
    • Relay Driver with Z-diode
    • Interference Protection (VDE 0839, ISO/TR 7637/1)
    • Load-dump Protection

    Application scenarios

    • Automotive wiper control
