BRD2365C
High-Voltage, Self-Powered, Half-bridge Motor Driver with Integrated Device Protection and System Monitoring. Up to 1 Horsepower Output. Lower than 12 mW Sleep Mode Consumption. Improved Fault Reporting.
Product Details
BridgeSwitch-2 expands available output to 1 horsepower (746 W), improves inverter efficiency to 99% and reduces sleep mode consumption to lower than 10mW.
The BridgeSwitch-2 family of integrated half-bridges dramatically simplifies the 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. The 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. BridgeSwitch-2 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.

BridgeSwitch-2 offers internal fault protection functions and external system level monitoring. Internal fault protection includes cycle-bycycle current limit for both FREDFETs and two level thermal overload protection. External system level monitoring includes DC bus sensing with four undervoltage levels and one overvoltage level as well as driving external sensors such as an NTC. The bi-directional bussed single wire status interface reports observed status changes. The new Sleep Mode reduces per device consumption to less than 4 mW from a rectified AC mains bus when using self-supplied operation.
