Description

The VNF1048F is an advanced controller for 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.
