EPC91132: 15 ARMS 3-Phase Motor Drive Inverter
The EPC91132 evaluation board is a 3-phase BLDC motor drive inverter board featuring
the EPC33110 three-phase co-packaged module that integrates three monolithic gallium nitride (GaN)
half-bridges, each featuring integrated gate drivers, bootstrap circuits, and level shifters. The board has
been designed with an optimized form factor for the small joints of humanoid robots and for 23 mm drone
motors.
The EPC33110 can deliver up to 16 Apk (11 ARMS) steady-state output current and up to 21 Apk (15 ARMS) pulsed
output while inserted inside the motor chassis.
The EPC91132 is intended for driving humanoid robot joints and contains all the necessary critical function
circuits to support a complete motor drive inverter, including a microcontroller, motor shaft angular
sensor, housekeeping power supplies, accurate voltage and current sense, NTC temperature sensing, SWD
connector and RS485 interface.
