POWER INTEGRATIONS BRD1267C-TL Datasheet & Stock

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.
