Half-Bridge Gate Driver IC Non-Inverting 8-SOIC
Active6,840 in stock

Overview

The FAN73901MX is a high-side and low-side gate drive IC designed to drive N-channel MOSFETs and IGBTs in half-bridge configurations. It operates with a floating channel up to 600V and features a high-current output of 2.5A to handle high-speed switching requirements. The device includes noise-canceling circuitry to improve reliability in high-voltage switching environments.

Why Choose This Part

This driver offers high peak sourcing and sinking current of 2.5A, which minimizes switching losses in power MOSFETs. It features matched propagation delays for both channels to prevent cross-conduction and includes under-voltage lockout (UVLO) for both high and low sides to ensure safe operation. The 600V floating channel is designed with common-mode dv/dt noise cancellation to prevent false triggering.

Applications

Brushless DC (BLDC) Motor Drives
Used in industrial and appliance motor controllers to drive high-voltage inverter stages.
Solar Inverters
Facilitates efficient high-side switching in DC-AC power conversion systems.
High-Voltage SMPS
Ideal for half-bridge and full-bridge switch-mode power supplies requiring fast 25ns rise times.
Induction Heating
Provides robust gate drive for high-frequency resonant power stages.

Getting Started

To evaluate this part, ensure the bootstrap capacitor is sized correctly for your switching frequency and gate charge requirements. Use a 10V to 20V supply for VDD and ensure logic inputs are either 3.3V or 5V compatible. Standard 8-SOIC prototyping adapters can be used for breadboard testing, though low-inductance PCB layouts are critical for high-current performance.
