DRV7308EVM

Overview

TopologyMotor Drive
Input voltage450 V
IC revisionA

Description

The DRV7308EVM is a module designed for thorough evaluation of the DRV7308 motor driver. The device is a 250W, 450V integrated triple gallium nitride (GaN) FET half-bridge gate driver for motor driver applications. The DRV7308EVM provides three 650V E-mode GaN FET half-bridges capable of directly driving a three-phase brushless-DC motor.The C2000™ LAUNCHXL-F2800137 LaunchPad™ is required for this kit and is used to operate and monitor the DRV7308 driver. PWM, fault response and further device control are provided by the LAUNCHXL-F2800137 module.

Features

Up to 450V operating voltage with 5A peak current drive capabilityLow conduction loss with GaN FET's 205mΩ RDS(ON) at TA = 25°CLow switching loss from zero reverse recoveryUltra-low adaptive dead time (<300ns)Ultra-low propagation delay (<135ns)Integrated bootstrap rectifier using GaN FET
