BridgeSwitch from Power Integrations
Bridging system protection into your electronics, BridgeSwitch allows you to build compact, high-voltage motor drives without using a physical heatsink.
The BridgeSwitch family of integrated half-bridges dramatically simplifies the development and production of high-voltage inverter driven single- or multi-phase synchronous and asynchronous motors like PM, BLDC, ACIM or switched reluctance motors. 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 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.

Protection Features
- Input Overvoltage
- Input Undervoltage
- Output Overvoltage
- Output Undervoltage
- Overtemperature
- System Temperature
- Thermal Overload
Control Features PMIC
- Remote Fault Reset
- Self-Biased Drivers
- Status Interface
BridgeSwitch offers internal fault protection functions and external system level monitoring. Internal fault protection includes cycle-by-cycle 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.
