Product details

The UCC27325PG4: The independent inverting and non-inverting input channels let you configure the drive polarity per channel without external logic. The 20 ns rise and 15 ns fall times (typical) keep switching losses low in the power FETs.

Supply range and logic thresholds — fitting into a 5V or 12V rail

The 4.5 V to 15 V supply range covers both 5 V and 12 V gate drive rails, which is the most common split in industrial and telecom power supplies. The logic input thresholds (VIL = 1 V, VIH = 2 V) are TTL/CMOS-compatible, so a 3.3 V microcontroller can drive the inputs directly without a level-shifter — a clean BOM simplification for mixed-voltage designs.

Military temperature range — where this driver survives

Rated for junction temperature from -55°C to 150°C, this driver is built for environments where commercial or even industrial parts fail: avionics, satellite power systems, downhole instrumentation, and high-reliability industrial motor drives. The 8-PDIP package (0.300" body, 7.62 mm width) is a through-hole footprint that suits prototyping, rework, and applications where vibration resistance or socketing is preferred over surface-mount.

That means no last-time-buy window to track, no end-of-life risk for the foreseeable production horizon.

Frequently asked questions

Is UCC27325PG4 a low-side or high-side gate driver?

It is a low-side gate driver. The driven configuration is low-side, meaning both outputs reference ground and are intended to drive the low-side MOSFETs in a buck converter, synchronous rectifier, or push-pull stage. It is not designed for high-side or half-bridge drive without an external bootstrap or isolated supply.

What is the peak output current of UCC27325PG4?

The peak output current is 4 A for both source and sink. That 4 A capability, combined with the 20 ns rise and 15 ns fall times, means the driver can charge and discharge the gate capacitance of a large MOSFET quickly, reducing the switching transition time and the associated power loss.

Can UCC27325PG4 be used with a 3.3V microcontroller input?

Yes. The logic input thresholds are 1 V for VIL and 2 V for VIH, so a 3.3 V logic output from an MCU or FPGA will reliably drive the inputs without any external level translation. This simplifies the interface in mixed-voltage designs.
