Product details

Single-channel low-side driver for IGBT and MOSFET gates

The supply range spans 10 V to 32 V, covering common 12 V and 24 V industrial and automotive rails without an intermediate regulator.

The driver is housed in a SOT-23-5 package (SC-74A, SOT-753), a 5-lead surface-mount footprint. The 0.95 mm lead pitch and compact body suit space-constrained designs, but the thermal dissipation relies on the PCB copper area under the part — the 140°C junction rating assumes adequate board-level heat sinking for continuous high-frequency switching.

Frequently asked questions

What is the difference between UCC27533 and UCC27531?

The UCC27533 is a single-channel driver with inverting and non-inverting inputs, while the UCC27531 is a single-channel driver with a single input and enable function. Both are low-side drivers in the same family, but the UCC27533 offers more input flexibility for designs that need complementary PWM control.

Is UCC27533DBVR compatible with 3.3V logic?

Yes, the logic thresholds are 1.2 V for VIL and 2.2 V for VIH, so a 3.3 V PWM output from a microcontroller or FPGA drives the input directly without level-shifting resistors.
