CRMM4614C CR Micro 30V 7A Complementary MOSFET SOP-8

The CR Micro CRMM4614C is a 30 V 7 A N-channel complementary MOSFET in a SOP-8 package. One N-channel and one P-channel die share the package. On-resistance is 22 mΩ typical and 26.4 mΩ maximum at a 10 V gate drive; 30 mΩ typical at 4.5 V, so it also works from a logic-level driver; threshold voltage spans 1 to 2.2 V.

Key Specifications

Same-Rating Selection Table

4 part numbers share the same 30 / SOP-8 / Complementary rating — sorted by config.

Applications

Low-voltage DC-DC converters, load switches, battery protection, and brushed or stepper motor drive.

Selection Notes

• The two dies share a package but not a thermal path. Check whether the configuration is complementary, dual, common drain or series before wiring it into a topology.
• In complementary parts the N and P dies have different Rds(on) and Qg. Match the drive separately rather than assuming symmetry.
• Common-drain parts suit load switch and battery protection circuits where the two sources tie together — the body diodes then oppose each other and block in both directions.
• Because both dies sit on one leadframe, total dissipation is limited by the package, not by the individual die ratings.

Common Questions

Is the CRMM4614C an N-channel or P-channel device?

It is N-channel. The drain-source rating is 30 V.

Can the CRMM4614C be driven from a 4.5 V logic-level gate signal?

Yes. The datasheet characterises Rds(on) at 4.5 V: 30 mΩ typical and 36 mΩ maximum.

What is the gate threshold voltage of the CRMM4614C?

VGS(th) is specified between 1 and 2.2 V. Below the lower figure the part is off; above the upper figure it is fully on at the rated current.

What package does the CRMM4614C come in?

SOP-8. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.

How do I choose between the 4 part numbers in this rating group?

All 4 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.
