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 capability at VDD = 12 V. 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 Not Restricted by VDD Pin Bias Supply Under Voltage Lockout (UVLO) circuitry on VDD pin Voltage holds output low outside VDD operating range. The • Operating Temperature Range of -40°C to capability to operate at low voltage levels such as 140°C below 5 V, along with best in class switching characteristics, is especially suited for driving • 5-Pin DBV Package (SOT-23) emerging wide band-gap power switching devices such as GaN power semiconductor devices.
