Product details

Half-bridge gate driver for N-channel MOSFETs

The MAX17491GTA+T is a half-bridge gate driver from Analog Devices, designed to drive two N-channel MOSFETs in a synchronous configuration. It accepts a non-inverting input and delivers 2A peak source current and 2.7A peak sink current per channel. The supply voltage range is 4.2V to 5.5V, and the bootstrap pin supports a high-side voltage up to 24V, covering the typical bias rail for a 12V or 24V bus converter. Rise and fall times are 10 ns and 8 ns typical, respectively, which keeps switching losses low in the 100 kHz–1 MHz range common for isolated DC-DC converters and point-of-load regulators.

Package and temperature grade

Housed in an 8-WQFN with exposed pad (supplier package 8-TQFN, 3x3 mm), the part is surface-mount and intended for reflow assembly.

Frequently asked questions

What is the peak output current of MAX17491GTA+T?

The peak output current is 2A source and 2.7A sink per channel, sufficient to drive the gate charge of medium-power MOSFETs in half-bridge topologies.
