UCC27511 Overview
The UCC27511 and UCC27512 single-channel, highspeed, low-side gate-driver device can effectively drive MOSFET and IGBT power switches. Using a design that inherently minimizes shoot-through current, UCC27511 and UCC27512 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 13 ns.
UCC27511 Key Features
- Low-Cost Gate-Driver Device Offering Superior Replacement of NPN and PNP Discrete Solutions
- 4-A Peak Source and 8-A Peak Sink Asymmetrical Drive
- Strong Sink Current Offers Enhanced Immunity Against Miller Turnon
- Split Output Configuration (Allows Easy and Independent Adjustment of Turnon and Turnoff Speeds) in the UCC27511 Saves 1
- Fast Propagation Delays (13-ns Typical)
- Fast Rise and Fall Times (9-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)
- TTL and CMOS patible Input-Logic Threshold (Independent of Supply Voltage)
- Hysteretic-Logic Thresholds for High-Noise Immunity
