typical)
The UCC27518 and UCC27519 single-channel, high-
speed, low-side gate driver device is capable of
• 4.5-V to 18-V Single Supply Range
effectively driving MOSFET and IGBT power
• Outputs Held Low During VDD UVLO (ensures
switches. Using a design that inherently minimizes
glitch free operation at power-up and power-
shoot-through current, UCC27518 and UCC27519
down)
are capable of sourcing and sinking high, peak-
• CMOS Input Logic Threshold (function of
current pulses into capacitive loads offering rail-to-rail
drive capability and extremely small propagation
supply voltage with hysteresis)
delay typically 17 ns.
• Hysteretic Logic Thresholds for High Noise
Immunity
The UCC27518 and UCC27519 provide 4-A source,
4-A sink (symmetrical drive) peak-drive current
• EN Pin for Enable Function (allowed to be no

connect)
The UCC27518 and UCC27519 are designed to
• Output Held Low when Input Pins are Floating
operate over a wide VDD range of 4.5 V to 18 V and
• Input Pin Absolute Maximum Voltage Levels
wide temperature range of -40°C to 140°C. Internal
