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
