Product overview
Description
The device is an advanced controller for a Power MOSFET in high-side configuration, designed for the implementation of an intelligent high-side switch for 12 V, 24 V, and 48 V automotive applications. The control IC is interfaced to a host microcontroller through a 3.3 V and 5 V CMOS-compatible SPI interface and provides protection and diagnostics to the system.
