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.

High side switch controller.

Because of how transistors work these can be a little more difficult to use in an arduino or raspberry pi circuit. A power good output indicates the status of the process side power supply. The device enlarges st s family of galvanic isolated high side switches. This transistor connects between v and the load.

Typically these use a pnp bjt or p channel mosfet. This requires both a robust low on resistance power switch and accurate analog circuitry for diagnostic protection and control functions. The max14922 is a high side n channel fet controller for implementing industrial high side switches for switching ground connected loads. 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. The galvanic isolated octal high side smart power switch enhances diagnostics and system management by providing a 20 mhz spi port allowing both per channel over temperature signalization and efficient daisy chaining of multiple devices. High side switches can safely drive high currents into complex resistive inductive and capacitive grounded loads in compliance with the harsh automotive environment.
