Description

Technical Parameters

The UCC21220DR isolated gate driver ensures efficient switching of MOSFETs and IGBTs with strong basic and functional isolation, high-speed performance (CMTI > 100V/ns) and powerful output (4A peak source, 6A peak sink). The device's switching parameters, including minimum propagation delay, precise delay matching, and low pulse-width distortion, enable reliable and precise timing control. It operates over a wide temperature range (-40°C to 125°C) and supports flexible drive supplies (up to 18V VDD) to accommodate different environments and voltage requirements. The UCC21220DR is available in a compact SOIC-16 (D) package for space-constrained applications. Additionally, its ability to suppress input pulses shorter than 5 ns further enhances the system's robustness. In summary, the UCC21220DR is a versatile, high-performance solution that sets a new standard for isolated gate drivers in power management systems.

Description:

The UCC21220 and UCC21220A devices are basic and functional isolated dual-channel gate drivers with 4-A peak-source and 6-A peak-sink current. They are designed to drive power MOSFETs and GaNFETs in PFC, Isolated DC/DC, and synchronous rectification applications, with fast switching performance and robust ground bounce protection through greater than 100-V/ns common-mode transient immunity (CMTI).

These devices can be configured as two low-side drivers, two high-side drivers, or half-bridge drivers. Two outputs can be paralleled to form a single driver which doubles the drive strength for heavy load conditions due to the best-in-class delay matching performance.

Protection features include: DIS pin shuts down both outputs simultaneously when it is set high; INA/B pin rejects input transient shorter than 5-ns; both inputs and outputs can withstand –2-V spikes for 200-ns, all supplies have undervoltage lockout (UVLO), and active pull down protection clamps the output below 2.1-V when unpowered or floated.

With these features, these devices enable high efficiency, high power density, and robustness in a wide variety of power applications.
