Product details

Last Buy — plan your final order

Buyers should secure their lifetime buy quantity now to avoid a forced redesign later.

9 A peak output — drives big gates fast

This single-channel low-side driver delivers 9 A peak source and 9 A peak sink current, with 20 ns typical rise and fall times. That current capability handles the gate charge of large N-channel and P-channel MOSFETs in power converters, motor drives, and switch-mode supplies without a separate booster stage.

4 V to 15 V supply — wide bias compatibility

The supply range from 4 V to 15 V lets the driver operate from standard 5 V, 12 V, or 15 V bias rails.

Through-hole 8-PDIP — rework-friendly footprint

The 8-PDIP package (0.300-inch body, 7.62 mm width) is a through-hole DIP that suits prototyping, low-volume builds, and applications where socketing or manual rework is preferred.

Frequently asked questions

Is UCC27321PE4 obsolete?

Texas Instruments lists the UCC27321PE4 as Last Buy, meaning it is in its final production phase. Once existing inventory is depleted, no further units will be manufactured. Plan a lifetime buy or identify a replacement before stock runs out.

Can UCC27321PE4 drive P-channel MOSFETs?

Yes. The gate type is specified for both N-channel and P-channel MOSFETs. The inverting input and single low-side configuration work with P-channel devices when the load and gate drive topology are arranged accordingly.
