3 Description
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.
