3 Description

The UCC27511A-Q1 device is a compact gate driver

that offers superior replacement of NPN and PNP

discrete driver (buffer circuit) solutions. The

UCC27511A-Q1 device is an automotive-grade

single-channel low-side, high-speed gate driver rated

for MOSFETs, IGBTs, and emerging wide-bandgap

power devices such as GaN. The device features fast

rise times, fall times, and propagation delays, making

the UCD27511A-Q1 device suitable for high-speed

applications. The device features 4-A peak source

and 8-A peak sink currents with asymmetrical drive,

boosting immunity against parasitic Miller turnon

effect. The split output configuration enables easy

and independent adjustment of rise and fall times

using only two resistors and eliminating the need for

an external diode.

•

Fast Propagation Delays (13-ns typical)

Fast Rise and Fall Times (9-ns and 7-ns typical)

4.5 to 18-V Single Supply Range

Outputs Held Low During V_DDUVLO (Ensures

Glitch-Free Operation at Power Up and Power

Down)

•

TTL and CMOS Compatible Input-Logic Threshold

(Independent of Supply Voltage)

Hysteretic-Logic Thresholds for High-Noise

Immunity

Dual-Input Design (Choice of an Inverting (IN–

Pin) or Non-Inverting (IN+ Pin) Driver

Configuration)
