CS5755SDQ CR Micro 500V 5A IPM QFN18

The CR Micro CS5755SDQ is a 500 V 5 A intelligent power module in a QFN18 package, wired as a half-bridge using MOSFET power stages. Protection on board covers under-voltage lockout. Designed for Fans and Hair dryer.

Key Specifications

Same-Rating Selection Table

19 part numbers share the same 500 / half-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 CS5755SDQ implement?

It is a half-bridge module rated 500 V / 5 A.

What protection is built into the CS5755SDQ?

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 CS5755SDQ intended for?

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

What package does the CS5755SDQ come in?

QFN18. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.

How do I choose between the 19 part numbers in this rating group?

All 19 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.
