EPC9176 20 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 28 Apk (20 ARMS) steady state output current.

The board can also be configured for multi-phase DC–DC conversion and the EPC23102 supports PWM switching frequencies up to 250 kHz in motor drive applications and 500 kHz in DC-DC applications.

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.




  • 3-phase inverter based on EPC23102 ePower™ Stage IC with wide input DC voltage ranging from 14 V to 65 V
  • Dimensions: L x W = 81 x 75 mm (including connector)
  • Low distortion switching that keeps motor audio emission low and reduces torque ripple
  • dv/dt optimized for motor drives less than 10 V/ns with option to increase dv/dt for DC–DC applications
  • Current sense, voltage sense, temperature monitoring circuit
  • Protection features including: over-current and input supply under voltage lockout
  • Shaft encoder/Hall sensors interface connector for motor drive application with two voltage levels selection option
  • The board can also be configured to operate as a synchronous buck DC–DC converter
