MikroElektronika High-Side Switch Controller With Intelligent E-Fuse Protection From STMicroelectronics MOSFET Driver

The MikroElektronika High-side switch Controller with intelligent fuse protection 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.
