MOSFET driver targets automotive apps

The A3942A four-channel high-side MOSFET control/driver IC drives four n-channel MOSFETs in a high-side configuration with gate drive outputs. It provides an interface between the system controller and high-current loads found in automotive engine control systems. The device operates from 4.5 to 60 V and over the automotive temperature range.

The four outputs are controlled with four parallel input lines or an integrated serial peripheral interface. The serial interface enables software control of channel-specific blanking times for short-to-ground detection. Multiple devices can share an SPI interface by either connecting them in parallel or in a daisy-chained series using the chip select pin to address the appropriate IC.
