The DRV81620-Q1 is an eight channel low-side and high-side switch with integrated protection and diagnostics. It is designed to control relays, LEDs, Lamps and motors in automotive and industrial applications.

A serial peripheral interface (SPI) with daisy chain capability is utilized for control and diagnosis of the loads as well as of the device. Two input pins with mapping functionality are available for direct control of the outputs. The device supports Limp Home mode for fail-safe activation. Integrated PWM generators enable driving LEDs, and bulb inrush mode enables driving loads with large capacitance.

The DRV81620-Q1 supports various protection features such as undervoltage, overvoltage, short circuit and open load detection. High level of integration with embedded protection and diagnostic features make the DRV81620-Q1 an ideal choice for automotive body and powertrain applications.
