What are the key features of UCC37321PE4?
- 9 A peak output current for fast MOSFET gate charging, reducing switching losses in power converters
- Totem-pole output stage delivers both high source and sink currents for symmetric gate drive waveforms
- 8-pin PDIP package with standard logic input threshold simplifies drop-in replacement in existing designs
What is UCC37321PE4 used for?
The UCC37321PE4 is designed for low-side MOSFET switching in DC-DC converters, synchronous rectifiers, and motor drive circuits requiring fast gate transitions. Its 9 A drive capability allows it to efficiently switch large power MOSFETs in buck, boost, and full-bridge topologies operating at frequencies up to several hundred kilohertz. It is also used in Class-D audio amplifiers and UPS inverter stages where precise gate timing is critical.

Frequently Asked Questions
How much gate-drive current can UCC37321PE4 deliver to a MOSFET?
UCC37321PE4 is specified with a 9 A peak output current, so it is intended for fast low-side MOSFET gate charging and discharging in power-control circuits.
Which package detail affects replacement planning for existing through-hole boards?
This version is supplied in an 8-pin PDIP package, making it relevant for legacy through-hole layouts that cannot directly accept SOIC or other surface-mount driver options.
When is this Texas Instruments driver suitable for a simple low-side switch stage?
It fits designs needing a 1-channel MOSFET driver with standard logic inputs and a totem-pole output, especially where 9 A peak drive helps reduce switching transition time.
