High side power switch mosfet.

Analog devices growing portfolio of high side switches and mosfet fet drivers provides a simple and effective solution to drive single dual triple or quad n channel or p channel fets. Although the p channel mosfet cannot. Tps2hb16 q1 is a 40 v 2 ch automotive aec q100 qualified high side switch with integrated 16 mω nmos that enables intelligent control of the variable kinds of resistive and inductive loads. 2 using bootstrap circuit in this method a single power source is needed using some capacitor in the circuit.

Typically these use a pnp bjt or p channel mosfet. Profet protected field effect transistors is our high side smart power switch brand. Yet despite its shortcomings the p channel mosfet performs a vital ªhigh sideº switch task that the n channel simply cannot equal. It consists of a mosfet a gate driver with charge pump and multiple protection and diagnosis features.

This transistor connects between v and the load. In this method the voltage is applied. Used as a high side switch a p channel mosfet in a totem pole arrangement with an n channel mosfet will simulate a high current high power cmos complementary mos arrangement. Because of how transistors work these can be a little more difficult to use in an arduino or raspberry pi circuit.

Then the p channel mosfet is used to switch the positive supply to the motor for forward direction high side switching while the n channel mosfet is used to switch the negative supply to the motor for reverse direction low side switching. The opposite of the low side switch is the high side switch. In addition several protection features are integrated. For example short circuit protection can protect the mosfet if a short to ground battery occurs.
