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.

TTL and CMOS Compatible Input Logic  
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.  
Hysteretic Logic Thresholds for High Noise  
Immunity  
Dual Input Design (choice of an inverting (IN-  
pin) or non-inverting (IN+ pin) driver  
configuration)  
–
Unused Input Pin can be Used for Enable  
or Disable Function  
•
•
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.
