Procurement Notes

Verify the component status before procurement, as availability may vary. Confirm that the P suffix indicates a lead-free leadframe construction. Ensure the design accommodates the specified thermal requirements, including heatsink flatness and mounting torque specifications. Validate that the application voltage and current ratings align with the module's absolute maximum ratings to ensure safe operation.

Selection Notes

Select this module for applications requiring a compact solution for driving small three-phase motors. The integrated HVICs simplify the design process by reducing inverter size and overall design time. Consider the 15kHz switching frequency capability when designing the control circuitry. Ensure the control supply voltage remains within the 13.5V to 16.5V range for proper operation of the internal logic and drivers.

FAQ

What is the maximum recommended PWM input frequency?

The maximum recommended PWM input frequency is 15 kHz, provided the junction temperature is kept at or below 125°C and the heatsink temperature is at or below 100°C.

How does the module handle short-circuit protection?

The module includes self-protection circuitry that detects short circuits on the low-arms. It triggers a fault output when the current sensing voltage exceeds the trip level, typically around 0.5V, and limits the collector-emitter voltage during the event.

What is the isolation voltage between the connection pins and the heatsink plate?

The isolation voltage is 2500 Volts AC for 1 minute at 60Hz sinusoidal waveform between the connection pins and the heatsink plate.
