Texas Instruments recently introduced the UCC27714 half-bridge gate driver for discrete power MOSFETs and IGBTs that operate up to 600 V. With 4-A source and 4-A sink current capability, the UCC27714 reduces component footprint by 50%. In addition, it provides 90-ns propagation delay, 40% lower than existing silicon solutions, tight control of the propagation delay with a maximum of 125 ns across –40°C to 125°C and tight channel-to-channel delay matching of 20 ns across –40°C to 125°C. The device eliminates the need for bulky gate drive transformers, saving significant board space in high-frequency switch-mode power electronics.
Key features and benefits include:
- Smaller footprint creates highest power-density solutions
- Advanced noise toleration
- MOSFETs have the ability to drive over a wide power range
- Operates across wide temperatures
The UCC27714 is now available. The high-speed 600-V, high-side low-side gate driver costs $1.75 in 1,000-unit quantities.
