Automotive 40V 8-channel high-side driver, 330mA per channel with limp home functionality

The DRV81080-Q1 is an 8-channel 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 DRV81080-Q1 an excellent choice for

automotive body and powertrain applications.
