The DRV81242-Q1 is an 8-channel low and high-side driver with protection and diagnostics. The device is designed to control relays, LEDs, lamps and motors.

A serial peripheral interface (SPI) with daisy chain is utilized for control and diagnosis of the loads and the device. Two input pins with mapping functionality allow direct control of the outputs. The device supports Limp Home for fail-safe activation. Integrated PWM generators enable driving LEDs, and bulb inrush mode enables driving loads with large capacitance. Clamp circuits on each output dissipates the energy during turning OFF inductive loads.

The device supports various protection features such as undervoltage, overvoltage, short circuit and open load detection. A high level of integration with embedded protection and diagnostic features make the DRV81242-Q1 an excellent choice for automotive body and powertrain applications.
