Product Overview

RDK-873 reference design kit is a 0.22ARMS, 30W, up to 95% efficient compact single-phase inverter design for a high-voltage single-phase brushless DC (BLDC) motor using BridgeSwitch motor driver IC. The inverter stage is implemented using two fully integrated BridgeSwitch (BRD1260C) devices in a full-bridge inverter configuration. The BridgeSwitch driver IC comes in a small footprint surface mount InSOP-24C package with exposed pads that enable heat sinking through PCB allowing a small form factor solution with few components. The board incorporates a simple control interface to the external controller facilitating the inverter control inputs and the BridgeSwitch additional features including a system sensing input, instantaneous phase current output and a single wire status update communication bus. In addition, an optional input for low-side device external-bias operation is provided for low no load input power requirement.
  • 270VDC to 365VDC input, 30W continuous inverter output power, 0.22A continuous motor RMS current
  • Single-phase inverter design for high-voltage BLDC applications using BRD1260C
  • Highly compact design with an inverter size of 25 x 30mm
  • Fully self-biased operation, no auxiliary power supply needed on the BridgeSwitch devices
  • Supports low side external bias operation for low no-load input power requirement
  • Integrated high side and low side cycle-by-cycle current limit on each BridgeSwitch devices
  • Device overtemperature protection
  • High voltage bus monitor with four undervoltage threshold and one overvoltage threshold
  • Instantaneous phase current output signal on each BridgeSwitch devices
  • Single wire status update communication bus, external system sensing input
