Power Driver Modules FAQ

What type of logic interface does the NFAM3512L7B use?

It uses an active logic interface that translates incoming logic-level gate inputs to the high-voltage, high-current drive signals required for the internal IGBTs.

How is the fault output signal configured?

The VFO pin provides a fault output signal which is an open-drain type. It requires a pull-up resistor to the positive side of the MCU or control power supply.

Can individual phase currents be sensed separately?

Yes, the module provides separate low-side IGBT emitter connections for each phase, allowing for individual current sensing of U, V, and W phases.
