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.

This transistor connects between v and the load. Mosfet as a switch. A drivers inputs are typically logic level. 2 using bootstrap circuit in this method a single power source is needed using some capacitor in the circuit.

While you can use a jfet for this circuit an enhancement mode mosfet works better. 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. For an n channel mosfet the source connects to ground and the drain connects to the negative side of the load. The opposite of the low side switch is the high side switch.

A high side p channel mosfet and a low side n channel mosfet tied with common drains figure 5 make a superb high current ªcmos equivalentº switch. Often mosfets require a 1 2a drive to achieve switching efficiently at frequencies of hundreds of kilohertz. 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. With our switch portfolio you can find a protection solution for your inductive capacitive and resistive loads ensuring your design is scalable and robust.
