Power Driver Modules FAQ

What type of logic inputs does the FSBB20CH60CL support?

The module features an active-HIGH input interface that works with 3.3 V or 5 V logic levels and utilizes Schmitt-trigger inputs for noise immunity.

How is the fault output signal configured?

The VFO pin provides a fault output signal corresponding to UVLO and short-circuit faults. It is an open-collector type that requires an external pull-up resistor, typically around 4.7 kΩ to 5 V.

Is short-circuit protection available for all phases?

Short-circuit protection is implemented only for the low-side IGBTs. The high-side IGBTs do not have integrated short-circuit protection circuitry.
