FAN7389MX1

FAIRCHILD SEMICONDUCTOR  FAN7389MX1  芯片, 栅极驱动器, 3路 半桥, 24SOIC

**Description**

The FAN7389 is a monolithic three-phase half-bridge gate-drive IC designed for high-voltage, high-speed

driving MOSFETs and IGBTs operating up to +600 V.

’s high-voltage process and common-mode noise canceling technique provide stable operation of

high-side drivers under high-dv/dt noise circumstances.

An advanced level-shift circuit allows high-side gate driver operation up to VS = -9.8 V typical for VBS =15 V.

The protection functions include under-voltage lockout and inverter over-current trip with an automatic fault

clear function.

**Features**

 Floating Channel for Bootstrap Operation to +600 V

 Typically 350 mA/650 mA Sourcing/Sinking Current Driving Capability for All Channels

 Extended Allowable Negative VS Swing to -9.8 V for Signal Propagation at VDD=VBS=15 V

 Output In-Phase with Input Signal

 Over-Current Shutdown Turns off All Six Drivers

 Matched Propagation Delay for All Channels

 3.3 V and 5.0 V Input Logic Compatible

 Adjustable Fault-Clear Timing

 Built-in Advanced Input Filter

 Built-in Shoot-Through Prevention Logic

 Built-in Soft Turn-Off Function

 Common-Mode dv/dt Noise Canceling Circuit

 Built-in UVLO Functions for All Channels

**Applications**

 3-Phase Motor Inverter Driver

 Air Conditioners

 Washing Machines

 General-Purpose Three-Phase Inverters
