typical)  
DESCRIPTION  
The UCC27518 and UCC27519 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, UCC27518 and UCC27519  
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 17 ns.  
•
•
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)  
•
•
•
CMOS Input Logic Threshold (function of  
supply voltage with hysteresis)  
Hysteretic Logic Thresholds for High Noise  
Immunity  
The UCC27518 and UCC27519 provide 4-A source,  
4-A sink (symmetrical drive) peak-drive current  
capability at VDD = 12 V.  
EN Pin for Enable Function (allowed to be no  
connect)  
The UCC27518 and UCC27519 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.
