UCC27511ADBVR +BOM

4-A/8-A single-channel gate driver with 5-V UVLO, split outputs, 5-V IN handling

UCC27511ADBVR General Description

By leveraging the device's asymmetrical 4-A peak source and 8-A peak sink currents, designers can confidently tackle challenging transient immunity issues. The split output configuration further enhances flexibility, enabling independent adjustment of rise and fall times using only two resistors and eliminating the need for an external diode.

Key Features

  • Input Pins Capable of Withstanding –5 V Below GND pin
  • Low-Cost Gate-Driver Device Offering Superior Replacement of NPN and PNP Discrete Solutions
  • Strong Sink Current Offers Enhanced Immunity Against Miller Turnon
  • Split Output Configuration (Allows Easy and Independent Adjustment of Turnon and Turnoff Speeds)
  • 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)
  • Wide Hysteresis (1-V typical) for High-Noise Immunity
  • Dual-Input Design (Choice of an Inverting (IN– Pin) or Non-Inverting (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
