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.
●The UCC27518 and UCC27519 provide 4-A source, 4-A sink (symmetrical drive) peak-drive current
●capability at VDD = 12 V.
●FEATURES
●• Low-Cost, Gate-Driver Device Offering Superior Replacement of NPN and PNP Discrete Solutions
●• Pin-to-Pin Compatible With TI"s TPS2828 and the TPS2829
●• 4-A Peak Source and 4-A Peak Sink Symmetrical Drive
●• Fast Propagation Delays (17-ns typical)
●• Fast Rise and Fall Times (8-ns and 7-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)
●• CMOS Input Logic Threshold (function of supply voltage with hysteresis)
●• Hysteretic Logic Thresholds for High Noise Immunity
●• EN Pin for Enable Function (allowed to be no connect)
●• Output Held Low when Input Pins are Floating
●• Input Pin Absolute Maximum Voltage Levels Not Restricted by VDD Pin Bias Supply Voltage
●• Operating Temperature Range of -40°C to 140°C
●• 5-Pin DBV Package (SOT-23)
●APPLICATIONS
●• Switch-Mode Power Supplies
●• DC-to-DC Converters
●• Companion Gate Driver Devices for Digital Power Controllers
●• Solar Power, Motor Control, UPS
●• Gate Driver for Emerging Wide Band-Gap Power Devices (such as GaN)
