Power Driver Modules FAQ

Does the FSBB20CH60B require external opto-couplers for gate driving?

No, the module utilizes a built-in High Voltage Integrated Circuit (HVIC) that enables opto-coupler-less single-supply IGBT gate driving.

How is short-circuit protection implemented in this module?

Short-circuit protection is provided for the low-side IGBTs only. It functions by detecting the short-circuit current and triggering a fault output signal after a specific delay determined by external components.

What is the purpose of the divided negative DC-link terminals?

The divided negative DC-link terminals allow for separate monitoring of each inverter phase current, facilitating precise current sensing applications.
