Industry’s fastest isolated gate driver for high-voltage applications

389982

The industry’s fastest 5.7-kVRMS isolated dual-channel gate driver, the first of a new gate driver family introduced by Texas Instrument isolation portfolio.

The UCC21520’s flexible, universal compatibility enables its use as an isolated driver in low-side, high-side, high-side/low-side or half-bridge power management designs. With its integrated components, advanced protection features and optimized switching performance, the UCC21520 enables designers to build smaller, more robust designs for enterprise, telecommunications, automotive and industrial applications.

Developed for high-voltage applications where system protection and reliability are critical, the UCC21520 provides reinforced isolation of 5.7 kVRMS and surge immunity tested up to 12.8 kV, along with common-mode transient immunity greater than 100 V/ns. By delivering the industry’s fastest propagation delay of 19 ns and the tightest channel-to-channel delay matching of less than 5 ns, the device enables high power density and efficiency, resulting in smaller solution size and reliable operation over end equipment lifetimes.

 

Key features

• Higher power density for smaller solutions: The 4-A source and 6-A sink current of the UCC21520 reduce switching losses via faster rise times of 6 ns and fall times of 7 ns for a 1.8-nF load in high-frequency switch-mode power applications.

• Isolation robustness: surge protection of up to 12.8 kV and noise immunity of greater than 10 V/ns.
• Flexibility: input voltage of 3 V to 18 V, programmable dead-time control, and dual channelling and paralleling of outputs.
• Low power consumption: standby power as low as 1 mA per channel.
