DESCRIPTION
The UCC27511 and UCC27512 single-channel, high-
speed, low-side gate driver device is capable of
effectively driving MOSFET and IGBT power
switches. Using a design that inherently minimizes
shoot-through current, UCC27511 and UCC27512
are capable of sourcing and sinking high, peak-
current pulses into capacitive loads offering rail-to-rail
drive capability and extremely small propagation
delay typically 13 ns.

typical)

•
4.5-V to 18-V Single Supply Range
Outputs Held Low During VDD UVLO (ensures
glitch free operation at power-up and power-
down)

Threshold, (independent of supply voltage)
The UCC27511 and UCC27512 provides 4-A source,
8-A sink (asymmetrical drive) peak-drive current
capability. Strong sink capability in asymmetrical drive
boosts immunity against parasitic, Miller turn-on
effect. The UCC27511 device also features a unique
split output configuration where the gate-drive current
is sourced through OUTH pin and sunk through
OUTL pin. This unique pin arrangement allows the
user to apply independent turn-on and turn-off
resistors to the OUTH and OUTL pins respectively
and easily control the switching slew rates.

Output Held Low when Input Pins are Floating
UCC27511 and UCC27512 are designed to operate
over a wide VDD range of 4.5 V to 18 V and wide
temperature range of -40°C to 140°C. Internal Under
Voltage Lockout (UVLO) circuitry on VDD pin holds
output low outside VDD operating range. The
capability 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.
