Product details

3A peak drive in an 8-SOIC — what it means on site

That drive strength is enough to switch the gate capacitance of a TO-220 or D2PAK power MOSFET in the tens-of-nanoseconds range — 8 ns typical rise, 7 ns typical fall — without needing an external booster stage. It runs from a single 8V to 17V supply, so a standard 12V rail (with its ±10% tolerance) lands right in the sweet spot.

Half-bridge topology, independent channels

The driven configuration is half-bridge — one high-side and one low-side output — with independent channel control. The high-side bootstrap supply is rated to 120 V maximum, which covers most 48V, 72V, and 100V bus applications. Input logic thresholds are 0.8V (VIL) and 2.5V (VIH), compatible with 3.3V and 5V PWM signals from a microcontroller or DSP. The non-inverting input type means the output follows the input polarity — no inversion stage to account for in the control loop.

Temperature grade and enclosure fit

That matters when a drive goes down on a production line and the spare kit has a soldering iron and a roll of solder wick.

Frequently asked questions

What is the difference between UCC27201 and UCC27201DR?

The base part is the same silicon. The UCC27201D variant typically ships in tubes. Electrically and functionally they are identical — same 3A drive, same 8V-17V supply, same 8-SOIC footprint. The DR suffix just changes the shipping medium for pick-and-place lines.

Can the UCC27201DR be used with a 12V supply?

Yes. The supply range is 8V to 17V, so a 12V rail — even with ±10% tolerance (10.8V to 13.2V) — sits comfortably within the operating window. The driver's internal undervoltage lockout (UVLO) thresholds are set to ensure clean startup and shutdown within this range.

How does the UCC27201DR compare to the UCC27211?

Both are half-bridge N-channel MOSFET drivers from TI in the same 8-SOIC package. The UCC27211 offers higher peak drive current — typically 4A source and 4A sink — compared to the UCC27201's 3A source and 3A sink. If your MOSFET gate charge is large enough that 3A cannot switch it within your dead-time budget, the UCC27211 provides extra headroom. Otherwise, the UCC27201DR is the more cost-effective choice for most 48V to 100V bus applications.
