Product details

Low-side gate driver with 9 A peak drive

The Texas Instruments UCC27322D is a single-channel low-side gate driver rated for 9 A peak source and sink current, making it a direct fit for driving the gate capacitance of medium-power N-channel and P-channel MOSFETs in switch-mode power supplies, DC-DC converters, and motor-drive stages. Supply range spans 4 V to 15 V. Typical rise and fall times of 20 ns keep switching losses low at moderate frequencies, and the non-inverting input simplifies control-loop polarity.

Logic-level compatibility and temperature range

Logic thresholds are set at 1.1 V for VIL and 2.7 V for VIH. Operating temperature covers -40°C to 105°C, which suits industrial enclosures, outdoor telecom cabinets, and under-hood automotive auxiliary circuits.

Package and mounting

Housed in an 8-pin SOIC package with 3.90 mm body width, the UCC27322D mounts on standard surface-mount pads and fits into a compact PCB layout alongside the driven MOSFET.

Lifecycle and compliance

The UCC27322D carries an Active product status and is ROHS3 compliant, so there is no last-time-buy risk for new designs or ongoing production.

Frequently asked questions

What is the peak output current rating of UCC27322D?

The peak output current is 9 A for both source and sink, which handles the gate charge of medium-power MOSFETs without excessive drive loss.

Can UCC27322D be used to drive P-channel MOSFETs?

Yes, the gate type is specified for both N-channel and P-channel MOSFETs, so it works with either polarity in low-side configurations.

Is UCC27322D compatible with 3.3 V logic?

Yes, with VIL at 1.1 V and VIH at 2.7 V, the driver accepts 3.3 V logic levels directly without external translation.
