High Side Switch Controller

This requires both a robust low on resistance power switch and accurate analog circuitry for diagnostic protection and control functions.

High side switch controller.

The n channel power mosfets typically have one third the on resistance of p channel mosfets of similar size and cost. Because of how transistors work these can be a little more difficult to use in an arduino or raspberry pi circuit. The device enlarges st s family of galvanic isolated high side switches. High side switches can safely drive high currents into complex resistive inductive and capacitive grounded loads in compliance with the harsh automotive environment.

The opposite of the low side switch is the high side switch. The max1614 drives high side n channel power mosfets to provide battery power switching functions in portable equipment. Typically these use a pnp bjt or p channel mosfet. The max14922 device controls an external nmos power transistor allowing low r on high side switch applications from a 9v to 70v supply range.

A power good output indicates the status of the process side power supply. Extreme switch devices are nxp smart high side switches for automotive 12 v bus truck 24 v and industrial applications. They belong to an expanding family designed to control protect and diagnose various types of loads with enhanced precision in bcm ecu or junction boxes.
