Applications
Fans and Hair dryer — the module's rating and package are sized for this class of load.
Selection Notes
- The module integrates gate drive and protection. The input side expects logic-level PWM, not a raw gate signal — do not add an external driver.
- Fault output is open-drain on most of these modules. Fit a pull-up and latch it in the controller, otherwise the module restarts into a fault.
- Check the dead time and minimum pulse width in the datasheet. The internal interlock is a protection layer, not a substitute for correct timing.
- Thermal design dominates reliability. Use the module's internal thermistor or the case-to-heatsink path to size the heatsink for the actual switching loss.
Common Questions
What topology does the CRM50T03FA implement?
It is a 3-phase full bridge module rated 500 V / 3 A.
What protection is built into the CRM50T03FA?
The module integrates under-voltage lockout. External fault handling still has to latch the fault signal and sequence a safe restart.
What applications is the CRM50T03FA intended for?
Fans and Hair dryer — a match for the module's power rating and package thermal path.
What package does the CRM50T03FA come in?
SOP-23A. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.
How do I choose between the 14 part numbers in this rating group?
All 14 share the same voltage and package class. Sort by on-resistance first, then check gate charge: the lowest Rds(on) part is not automatically the best choice if the stage switches at high frequency. The table above lists them in ascending Rds(on) order.
