Mosfet High Side Switching

Here the operating conditions of the transistor are zero input gate voltage v in zero drain current i d and output voltage.

Mosfet high side switching.

The opposite of the low side switch is the high side switch. 2 using bootstrap circuit in this method a single power source is needed using some capacitor in the circuit. This transistor connects between v and the load. Mosfet as a switch.

For an n channel mosfet the source connects to ground and the drain connects to the negative side of the load. Circuit diagram of mosfet as high side switch 1 dual power supply this method is very simple but it needs two power source. While you can use a jfet for this circuit an enhancement mode mosfet works better. Often mosfets require a 1 2a drive to achieve switching efficiently at frequencies of hundreds of kilohertz.

In this method the voltage is applied. With adjustable current limit high accuracy current sense and a wide range of rdsons our smart high side switches provide the optimal solution for your specific use case. A drivers inputs are typically logic level. One fault common to such circuits has been the excessive crossover current during switching that may occur if the gate drive allows both mosfets to be on simultaneously.

With our switch portfolio you can find a protection solution for your inductive capacitive and resistive loads ensuring your design is scalable and robust.
