EPC EPC33110 3-Phase ePower™ Stage IC

Efficient Power Conversion (EPC) EPC33110 3-Phase ePower™ Stage Integrated Circuit (IC) is co-packaged with integrated gate drivers, level shifters, and bootstraps for compact, high-power-density motor control. The EPC33110 features an absolute maximum input voltage of 100V, a continuous power-stage load current of 20A, and 3.3V/5V logic levels. The module uses EPC's proprietary GaN® IC technology, resulting in a power-stage IC that translates logic-level control signals into a high-voltage and high-current power stage. This process makes it simpler to design, easier to manufacture, and smaller in size - all while being more efficient to operate. EPC EPC33110 3-Phase ePower Stage IC comes in a 6.5mm x 6mm thermally enhanced QFN package with an exposed top for low thermal resistance to top-side heatsinking and wettable flanks for inline automated optical inspection (AOI).

Features

  • 3-phase integrated power module
  • Each phase integrates high-side and low-side eGaN® FET with internal gate driver and level shifter
  • Independent high-side and low-side control inputs for all phases
  • Logic lockout commands both FETs off when inputs are both high at same time
  • Synchronous charging for high-side bootstrap supplies
  • Robust level shifter operation for hard and soft switching conditions
  • Standby function for low quiescent current mode
  • Fast PWM shutdown when (SD/STB) pulled low
  • Power-on-reset for low-side and high-side power supplies
  • Power stage high impedance guaranteed in absence of VDRV/VBOOT supplies
  • 0% and 100% duty capable

Applications

  • Motor drive inverters (BLDC/PMSM)
  • Humanoid and collaborative robots (elbow/wrist/ankle joints)
  • Miniature motors for industrial automation
  • Small-payload drones and gimbals

Specifications

  • 20A continuous power stage load current TJ = +25°C
  • 3MHz maximum operating PWM frequency
  • 100V absolute maximum input voltage
  • 80V operating input voltage range
  • 5V nominal bias supply voltage
  • 11.7mΩ + 13mΩ typical RDS(on)
  • 3.3V/5V logic levels
  • Thermally enhanced QFN package with exposed top for low thermal resistance to top-side heatsinking, wettable flanks for inline AOI
  • 6.5mm x 6mm package size
