EPC EPC2366 | Demoboard EPC91121

Overview

TopologyMotor Drive
Input voltage18-30 V
IC revision1.1

Description

The EPC91121 evaluation board is a 3-phase BLDC motor drive inverter board featuring the EPC2366 eGaN FET 0.84 mΩ typical RDS(on) 40 V maximum device voltage intended for batteries up to 30 V. The EPC91121 can deliver up to 70 Apk (50 ARMS) maximum output current. The board supports PWM switching frequencies up to 150 kHz in motor drive applications.The EPC91121 contains all the necessary critical functions circuits to support a complete motor drive inverter including gate drivers, regulated auxiliary power rails for housekeeping supplies, voltage, and temperature sense, accurate current sense, and protection functions.The EPC91121 mates with an assortment of compatible controllers, supported by various manufacturers leveraging existing resources for quick development purposes, that can quickly be configured as a motor drive inverter.

Features

3-phase inverter based on EPC2366 GaN FET with wide input DC voltage ranging from 18 V to 30 VDimensions: L x W = 79 mm x 80 mm (including connector)Low distortion switching that keeps motor audio emission low and reduces torque rippledv/dt optimized for motor drives less than 10 V/nsCurrent sense, voltage sense, temperature monitoring circuitInput supply under voltage lockoutShaft encoder/Hall sensors interface connector for motor drive application with two voltage levels selection option

Typical applications

  • BLDC motor drives for Handheld power tools, Humanoid Robot Joints, Drones
