Power Driver Modules Procurement Notes

Verify the specific ordering suffix 'L7B' against the manufacturer's latest documentation to ensure correct configuration. Confirm that the DIP39 package dimensions and pinout align with the target PCB layout. Ensure the control supply voltage remains within the recommended operating range of 13.5 V to 16.5 V during system validation.

Power Driver Modules Selection Notes

Select this module for applications requiring integrated protection features such as under-voltage lockout and over-current shutdown. The separate negative DC-link inputs allow for flexible control algorithms and individual current sensing. Ensure the heatsink flatness tolerance is maintained between -50 µm and +100 µm for optimal thermal performance.

Power Driver Modules FAQ

How is the fault output signal configured?

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

What is the function of the VTS pin?

The VTS pin outputs a voltage proportional to the temperature of the Low-Voltage IC (LVIC). It is intended for temperature sensing and does not automatically shut down the IGBTs.

Can individual phase current sensing be performed?

Yes, the module provides separate negative IGBT terminals (NU, NV, NW) for each phase to support individual current sensing.
