RDK-851

50W high voltage brushless DC (BLDC) motor for fan application. The 3-phase inverter uses BridgeSwitch (BRD1260C). This solution offers <gt/>93% efficiency requires no heat sink and is designed for 270VDC – 365VDC input, 50W continuous inverter output power and 0.22A continuous motor RMS current. The design incorporates a complete inverter stage with a control input interface to facilitate various control schemes with the addition of a system sensing input, instantaneous phase current output signals from each BridgeSwitch device, a status communication bus output and an optional input for device external-bias operation. PCB size customized for inverter fan designs (88mm diameter round shaped PCB in double-sided layout).

• BridgeSwitch high-voltage half-bridge motor driver
• Integrated 600V FREDFETs with ultra-soft, fast recovery diodes
• Three-phase inverter design for high-voltage BLDC fan applications up to 50W
• Fully self-biased operation on the BridgeSwitch devices with an on-board external bias option
• Instantaneous phase current output signal on each BridgeSwitch device
• Single wire status update communication bus, device over-temperature protection
• External system sensing input
• Integrated high-side and low-side cycle-by-cycle current limit on each BridgeSwitch devices
• Supports trapezoidal and sinusoidal commutation control schemes
• High voltage bus monitor with four undervoltage threshold and one overvoltage threshold
