Ideal Diode and High Side Switch NMOS Controller

The NCV68261 is a Reverse Polarity Protection and Ideal Diode NMOS Controller with optional High Side Switch function, intended as a lower loss and lower forward voltage replacement for power rectifier diodes and mechanical power switches. The controller operates in conjunction with one or two N−channel MOSFETs and sets the ON/OFF state of the transistors based on the state of the Enable pin and the Input-to-Drain differential voltage polarity. Depending on the Drain pin connection, both Ideal Diode and High Side Switch applications can operate in two different modes. With the Drain pin connected to the load, the applications are in Ideal Diode mode, whereas with the Drain pin connected to ground, the applications are merely in Reverse Polarity Protection mode.
