UCC27511A (ACTIVE)

Single-Channel High-Speed Low-Side Gate Driver With 4-A Peak Source and 8-A Peak Sink

 

Description

The UCC27511A device is a compact gate driver that offers superior replacement of NPN and PNP discrete driver (buffer circuit) solutions. The UCC27511Asingle-channel low-side, high-speed gate driver rated for MOSFETs, IGBTs, and emerging wide-bandgap power devices such as GaN. The device features fast rise times, fall times, and propagation delays, making the UCC27511A device suitable for high-speed applications. Its asymmetrical 4-A peak source and 8-A peak sink currents boost immunity against parasitic Miller turnon effect. The split output configuration enables easy and independent adjustment of rise and fall times using only two resistors and eliminating the need for an external diode. Features including wide input hysteresis and negative input voltage handling enhance transient immunity.

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)
