EPC9173 35 ARMS 3-Phase BLDC Motor Drive Reference Design Board

EPC9173 Development Kit

The EPC9173 demonstration board is a 3-phase BLDC motor drive inverter board featuring the EPC23101 ePower™ Stage IC.

The EPC9173 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 board can also be configured for multi-phase DC–DC conversion.

The EPC9173 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 or DC–DC converter.
