CRMT5002E1 CR Micro 500V 4A IPM SOP-23A

The CR Micro CRMT5002E1 is a 500 V 4 A intelligent power module in a SOP-23A package, wired as a 3-phase full bridge using MOSFET power stages. Protection on board covers under-voltage lockout. Designed for Fans and Hair dryer.

Key Specifications

Same-Rating Selection Table

14 part numbers share the same 500 / 3-phase full bridge rating — sorted by current.

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 CRMT5002E1 implement?

It is a 3-phase full bridge module rated 500 V / 4 A.

What protection is built into the CRMT5002E1?

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 CRMT5002E1 intended for?

Fans and Hair dryer — a match for the module's power rating and package thermal path.

What package does the CRMT5002E1 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.
