Contact Monitoring and Dual Low Side Protected Driver

The MC33287 has been designed to interface between switching contacts (to battery or ground) and a microcontroller. This circuit includes 2 low side drivers, resistive and inductive loads or lamps.

• 8 High Voltage Input Triggers :
    - 1 Direct Output and 7 Multiplexed,
    - Direct Interface with Microcontroller
• 2 Low Side Drivers
    - Current Limitation : Ilim Typ = 0.5A (Each Output)
    - Internal Clamp : Vclamp Typ = 50V
    - Low Power Consumption in Standby Mode : Imax = 110µA
    - Overtemperature Protection (Typical 160°C)
    - Outputs Fault Detection
