R3500 Series
42 V Input 4ch Window Voltage Detector with Diagnostic Function

  • Description

    The R3500 is a 4ch window voltage detector with manual reset function suited for systems requiring functional safety. This device monitors over and under voltage from the multiple power supplies to SoCs, memories and sensors to continuously supervise the system operating at normal voltage.

    Key Benefits

    • Power supply from battery enables the voltage detector to operate independently from the power source.
    • High-accuracy detection of the over and under voltages from -1.25% to 0.75% and the hysteresis of Max. 0.75%.
    • Management of multiple power supplies with a single chip to save space.
