Description
●The UCC27516 and UCC27517 single-channel, high speed, low-side gate driver devices can effectively drive MOSFET and IGBT power switches. Using a design that inherently minimizes shoot-through current, UCC27516 and UCC27517 can source and sink high peak-current pulses into capacitive loads offering rail-to-rail drive capability and extremely small propagation delay, typically 13 ns.
●Features
●• Low-Cost Gate-Driver Device Offering Superior
● Replacement of NPN and PNP Discrete Solutions
●• 4-A Peak-Source and 4-A Peak-Sink Symmetrical Drive
●• Fast Propagation Delays (13-ns Typical)
●• Fast Rise and Fall Times (9-ns and 7-ns Typical)
●• 4.5 to 18-V Single-Supply Range
●• Outputs Held Low During VDD UVLO (Ensures Glitch-Free Operation at Power Up and Power Down)
●• TTL and CMOS Compatible Input-Logic Threshold (Independent of Supply Voltage)
●• Hysteretic-Logic Thresholds for High-Noise Immunity
●• Dual Input Design (Choice of an Inverting (IN–pin) or Noninverting (IN+ Pin) Driver Configuration)
●– Unused Input Pin Can Be Used for Enable or Disable Function
●• 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 (SOT-23) and 6-Pin DRS (3-mm × 3-mm WSON With Exposed Thermal Pad) Package Options
●Applications
●• Switched-Mode Power Supplies
●• DC-DC Converters
●• Companion Gate-Driver Devices for Digital-Power Controllers
●• Solar Power, Motor Control, UPS
