Mosfet High Side Switching

For an n channel mosfet the source connects to ground and the drain connects to the negative side of the load.

Mosfet high side switching. Driver ic s are often used for high current mosfets and when using fast switching rates due to the mosfet needing brief but high currents to change state. A drivers inputs are typically logic level. Here the operating conditions of the transistor are zero input gate voltage v in zero drain current i d and output voltage. N channel p channel 15.

Circuit diagram of mosfet as high side switch 1 dual power supply this method is very simple but it needs two power source. Mosfet as a switch. This transistor connects between v and the load. In this method the voltage is applied.

With our switch portfolio you can find a protection solution for your inductive capacitive and resistive loads ensuring your design is scalable and robust. 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. The opposite of the low side switch is the high side switch. 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.

2 using bootstrap circuit in this method a single power source is needed using some capacitor in the circuit.
