Overview
This device is a compact gate driver that serves as an excellent replacement for NPN and PNP discrete driver (buffer circuit) solutions. The driver supports MOSFETs, IGBTs, and emerging wide-bandgap power devices such as GaN, making it suitable for high-speed applications. Its asymmetric 4-A peak source current and 8-A peak sink current enhance immunity to parasitic Miller turn-on. Features including wide input hysteresis and negative input voltage handling capability improve transient noise immunity.
Applications
- DC-DC converters
- Desktop power supplies
- Switching power supplies
- Companion gate drivers for digital power controllers
- Gate drivers for emerging wide-bandgap power devices (e.g., GaN)
Key features
- 4.5 to 18-V single-supply range
- Output held low during VDD UVLO
- TTL and CMOS compatible input logic thresholds
- Output held low when input pins are floating
- Fast rise and fall times (typical 9ns and 7ns)
- Fast propagation delay (typical 13ns)
- Split-output configuration
- Strong sink current for enhanced Miller turn-on immunity
- Input pins withstand voltages -5 V below GND pin
- Compact package: SOT23-5
