Product details

The UCC27611DRVR is a single-channel low-side gate driver from Texas Instruments, built to drive N-channel MOSFETs. Its headline numbers are a 4 A peak source current and a 6 A peak sink current, with 5 ns typical rise and fall times. That combination means it can charge and discharge the gate capacitance of a medium-power MOSFET fast enough to keep switching losses in check — think DC-DC converters, synchronous rectifier stages, and primary-side switches in isolated supplies.

Supply rail and logic interface

The driver operates from a 4 V to 18 V supply rail, covering the common 5 V, 12 V, and 15 V gate drive voltages used in most offline and intermediate-bus converters. Logic input thresholds are 1.3 V (VIL) and 1.85 V (VIH), so it interfaces directly with 1.8 V and 3.3 V PWM controllers or MCU outputs without a level-shifter. Both inverting and non-inverting input options are available on the same package — the designer chooses the polarity that matches the controller output without adding an external inverter gate.

Frequently asked questions

Does UCC27611DRVR support inverting and non-inverting inputs?

Yes. The driver accepts both inverting and non-inverting input signals on the same device, selectable by which input pin is driven.

Can UCC27611DRVR drive multiple MOSFETs?

It depends on the total gate charge of the parallel MOSFETs and the switching frequency. With 4 A peak source and 6 A peak sink capability, the driver can handle a combined gate charge of several tens of nC per switching cycle. For example, driving two 15 nC MOSFETs at 500 kHz is within its capability, provided the gate drive loop inductance is kept low and the supply decoupling is adequate. For higher total gate charge or higher frequency, verify the average gate drive power against the package thermal limits.
