What is a MOSFET driver IC?

A MOSFET driver IC translates TTL or CMOS logical signals, to a higher voltage and higher current, with the goal of rapidly and completely switching the gate of a MOSFET. An output pin of a microcontroller is usually adequate to drive a small-signal logic level MOSFET.

What is the peak output of the power MOSFET drivers?

Power MOSFET Drivers Product Peak Output Current (source/sink, A) Capacitive Load Drive MIC5011 950uA* 1000 pF in 60 µs MIC5013 225uA* 1000 pF in 60µs MIC5014 800uA* 1000 pF in 90 µs MIC5015 800uA* 1000 pF in 90 µs

Why is a MOSFET used in a switch?

In most applications, a system is in need of a switch to be able to work correctly. Since there is no ideal switches, most of the time, the component chosen for this task is a MOSFET. A MOSFET usually needs a gate driver to do the on/off operation at the desired frequency.

How do I find the internal capacitors of a MOSFET?

A MOSFET has various internal capacitors that play a big part on the switching operations. The values of these capacitors can be found by looking at the datasheet and using the following equations: Another parameter to look for is the total gate charge.

Why is the gate current of a MOSFET drive high?

So, a high gate drive current such as the current from a MOSFET drive IC can save a lot of power and hence heat by speeding up the MOSFET switching. One of the reasons for the delay in the switch on/off is the charge storage in the channel rather than simply the capacitance of the gate.

What is gate driver in microcontroller?

Gate Driver. A MOSFET driver IC translates TTL or CMOS logical signals, to a higher voltage and higher current, with the goal of rapidly and completely switching the gate of a MOSFET. An output pin of a microcontroller is usually adequate to drive a small-signal logic level MOSFET.
