STMicroelectronics VNF1248F High-Side Switch Controller offers a power MOSFET in a high-side configuration. The STMicro VNF1248F is developed for implementing an intelligent high-side switch in 12V, 24V, and 48V automotive applications. The control IC is interfaced to a host microcontroller via a 3.3V and 5V CMOS-compatible SPI interface and supplies protection and diagnostics for the system.
