Product details

The UCC27523D: It drives both N-channel MOSFETs and IGBTs, with a supply range of 4.5V to 18V that covers common gate-drive rails for industrial and telecom power stages. The inverting input logic (VIL = 1V, VIH = 2.3V) means the output goes high when the input is pulled low — handy for designs where the PWM controller has an active-low output or you need to invert the control signal without an extra inverter gate.

Switching speed and gate charge budget

Rise and fall times are 7ns and 6ns typical, respectively. That edge rate keeps switching losses low in the power FET or IGBT, but it also means the layout loop from the driver output to the gate resistor and back to the source/emitter needs to be tight — a few nH of stray inductance will ring the gate waveform. Each channel operates independently, so you can drive two separate power devices with independent PWM signals, or parallel the two channels for a single device needing higher peak current (10A effective) by tying the inputs and outputs together.

Frequently asked questions

Can UCC27523D drive both IGBT and MOSFET?

Yes, the gate type is specified for both IGBT and N-channel MOSFET. The 5A peak drive and 4.5V to 18V supply range cover the gate charge requirements of most small-to-medium power devices in each class.

What is the input type of UCC27523D?

The input type is inverting. The logic thresholds are VIL = 1V and VIH = 2.3V, so a low input (below 1V) turns the output on, and a high input (above 2.3V) turns the output off.
