FAN7190MX

Gate Driver Overview

The FAN7190MX is a high-current, dual-channel gate driver IC designed for driving IGBTs and MOSFETs in hard-switching applications. It integrates both high-side and low-side drivers within a single SOIC-8 package. The device delivers a peak output current of 4.5 A to ensure fast switching transitions. It operates with a supply voltage range from 10 V to 22 V. The typical rise and fall times are 20 ns, supporting high-frequency operation. Maximum turn-on and turn-off delay times are specified at 200 ns. The component functions reliably across an extended temperature range from -40°C to +125°C.

Gate Driver Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm exact packaging and tape-and-reel specifications. Confirm that the selected variant meets all required automotive or industrial qualification standards if applicable. Ensure compatibility with the intended PCB footprint and thermal management requirements before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a compact solution is required for driving two power switches in a half-bridge topology. The integrated design reduces board space compared to discrete driver solutions. Consider the 4.5 A drive capability for medium-power applications requiring fast switching speeds. Verify that the operating voltage range aligns with the bootstrap or isolated supply available in the target system design.
