EPC9176: 25 ARMS 3-Phase Motor Drive Inverter

EPC9176 25 ARMS 3-Phase BLDC Motor Drive Inverter
Reference Design Board

EPC9176 Development Kit

The EPC9176 demonstration board is a 3-phase BLDC motor drive inverter board featuring the EPC23102 ePower™ Stage IC 6.6 mΩ maximum RDS(on), 100 V maximum device voltage. The EPC9176 can deliver up to 35 Apk (25 ARMS) steady state and 40 Apk pulsed output current.

The EPC9176 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 EPC9176KIT includes:

One (1) EPC9176 evaluation board
One (1) EPC9147A controller board
One (1) EPC9147E controller board

Features

  • 3-phase inverter based on EPC23102 ePower™ Stage IC with wide input DC voltage ranging from 14 V to 80 V
  • Dimensions: L x W = 81 x 75 mm (including connector)
  • Low distortion switching that keeps motor audio emission low and reduces torque ripple
