Power Driver Modules FAQ

How is short-circuit protection implemented in the FSBM20SH60A?

Short-circuit protection is realized through advanced current sensing IGBT chips located on the low side, allowing continuous monitoring of the IGBT current and triggering a fault signal if thresholds are exceeded.

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

The divided negative dc-link terminals (NU, NV, NW) facilitate inverter current sensing applications by providing separate connection points for each phase's return path.

Can the FSBM20SH60A be driven by a single supply voltage?

Yes, the incorporated High Voltage Integrated Circuit (HVIC) facilitates the use of a single-supply drive topology, enabling the module to be driven by only one drive supply voltage without negative bias.
