- Fast Rise and Fall Times (8ns and 7ns typical)
- 4.5V to 18V 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 (1V 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
The UCC27511A device is a compact gate driver that offers superior replacement of NPN and PNP discrete driver (buffer circuit) solutions. The UCC27511A device is a single-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 4A peak source and 8A 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.
