GaN ICs drive robotics and motion control

Four 100-V GaN power-stage ICs from EPC are optimized for motor drives in humanoid robots, drones, and battery-powered platforms. The EPC23108, EPC23109, EPC23110, and EPC23111 integrate a gate driver, high- and low-side eGaN FETs, and level-shifting circuitry in a half-bridge configuration. They support operation up to 100 V with load currents of 35 A (EPC23108, EPC23109) and 20 A (EPC23110, EPC23111).

The control interface includes an active-low fast-shutdown and standby input with a 65-kΩ pull-up. It meets industrial logic standards, letting designers connect directly to standard controllers. This simplifies designs and ensures consistent operation across platforms. Safety is enhanced through deterministic shutdown. 

The series supports continuous 100% duty-cycle operation, enabling full-torque and uninterrupted conduction in motion control, robotics, and precision regulation systems. The EPC23109 and EPC23111 offer a single-pin PWM input with enable logic and fixed dead time, simplifying multi-axis designs. The EPC23108 and EPC23110 feature dual PWM inputs for adaptive dead-time modulation.

Engineering samples are available for qualified designs. The EPC23108, EPC23109, EPC23110, and EPC23111 can be ordered through EPC’s distributor partners.
