UCC27518A-Q1, UCC27519A-Q1
SLVSC90B –AUGUST 2013–REVISED AUGUST 2015
UCC2751xA-Q1 Single-Channel High-Speed Low-Side Gate Driver With Negative Input
Voltage Capability
1 Features
3 Description
The UCC2751xA-Q1 single-channel high-speed low-
side gate driver devices effectively drive MOSFET
and IGBT power switches. With a design that
inherently minimizes shoot-through current, the
UCC2751xA-Q1 family of devices sources and sinks
high, peak-current pulses into capacitive loads
offering rail-to-rail drive capability and extremely small
propagation delay typically 17 ns.

Low-Cost Gate-Driver Device Offering Superior
Replacement of NPN and PNP Discrete Solutions
Pin-to-Pin Compatible With TI's TPSS2828-Q1
and the TPS2829-Q1
The UCC2751xA-Q1 family of devices operates over
a wide VDD range of 4.5 V to 18 V and wide
temperature range of –40°C to 140°C. Internal
undervoltage lockout (UVLO) circuitry on VDD pin
holds output low outside VDD operating range. The
ability to operate at low voltage levels such as below
5 V, along with best in class switching characteristics,
is especially suited for driving emerging wide band-
gap power switching devices such as GaN power-
semiconductor devices.

The input pin threshold of the UCC2751xA-Q1 family
of devices is based on CMOS logic where the
threshold voltage is a function of the VDD supply
voltage. Typically, the input high threshold (VIN–H) is
55% VDD and the input low threshold (VIN–L) is 39%
VDD. Wide hysteresis (16% VDD typically) between the
high and low thresholds offers excellent noise
immunity and allows users to introduce delays using
RC circuits between the input PWM signal and the
INx pin of the device.
