BridgeSwitch� family of integrated half-bridges dramatically simplifies development and production of high voltage inverter driven 1- or 3-phase PM or BLDC motor drives. It incorporates two high voltage N-channel power FREDFETs with low and high-side drivers in a single small-outline package. Internal power FREDFETs offer ultra-soft and ultrafast diodes ideally suited for hard switched inverter drives. Both drivers are self-supplied eliminating the need for an external auxiliary power supply. It provides a unique instantaneous phase current output signal simplifying implementation of sensor-less control schemes. The low-profile, compact footprint surface mount package offers extended creepage distances and allows heat sinking of both power FREDFETs through the printed circuit board. Used in 1 or 3-phase high voltage PM/BLDC motor drives, up to 400W typical inverter output power, appliances (dish washers, refrigerators), condenser fans in high efficiency air conditioners.
- FREDFET DC output current of 11.5A, continuous phase RMS current of 1.33A
- Highest performance and design flexibility, enhanced safety and reliability features
- Fully integrated half-bridge stage with up to 99.2% efficiency
- 600V N-channel power FREDFETs, ultra-soft, fast recovery diode
- Self-biased low-side and high-side drivers eliminates need for auxiliary power supply
- Small footprint surface mount InSOP-24C package, exposed pads enable heat sinking through PCB
- Adjustable cycle-by-cycle current limit for both FREDFETs, fail-safe operation
- Internal dual level thermal overload protection, self-configuring system level monitoring input
- Bi-directional bussed open drain single wire interface, reports status updates to system MCU
- Status query through system MCU, device fault reset through system MCU
