Overview
The UCC21520DW is a dual-channel reinforced isolated gate driver from Texas Instruments, designed for driving power MOSFETs, IGBTs, and SiC MOSFETs up to 5MHz. It features a peak output current of 6A on one channel and 4A on the other, with a supply voltage range of 6.5V to 25V. The device provides an isolation voltage of 5700 Vrms and operates within a temperature range of -40°C to 125°C. Key timing parameters include a maximum propagation delay of 45ns, rise time of 16ns, and fall time of 12ns. Packaged in a 16-pin SOIC, it supports programmable deadtime and includes disable functionality.
Feature Summary
- Reinforced isolation capability with 5700 Vrms rating for high-voltage applications
- Dual-channel architecture providing independent control for half-bridge configurations
- Programmable deadtime generation to prevent shoot-through in power switches
- Integrated disable pin for enhanced system safety and control flexibility
Applications
- Industrial motor drives and inverters
- Solar micro-inverters and string inverters
- Uninterruptible power supplies (UPS)
- High-frequency DC-DC converters
Procurement Notes
Verify that the specific order matches the UCC21520DW suffix to ensure the correct SOIC-16 package variant. Confirm that the application requirements align with the 5700 Vrms isolation rating and the specified operating temperature range. Ensure proper layout practices are followed to maintain signal integrity and isolation performance during implementation.
Selection Notes
Select this component when high-speed switching of wide-bandgap devices like SiC MOSFETs is required. The dual-channel design simplifies half-bridge driver implementations compared to single-channel alternatives. Consider the 6A/4A asymmetrical output currents if driving different sized switches or managing asymmetric load conditions efficiently.
Part Context
This part belongs to the UCC21520 family of isolated gate drivers. It complements variants such as the UCC21520DWR (tape and reel) and automotive-grade UCC21520QDWQ1. The DW suffix specifically denotes the standard SOIC-16 surface-mount package suitable for general industrial and commercial power electronics designs.
Replacement Considerations
The UCC21520DWR serves as a direct packaging alternative offering identical electrical characteristics but in tape-and-reel format. For automotive applications requiring AEC-Q100 qualification, the UCC21520QDWQ1 is the appropriate substitute. No functional changes are implied by these suffix variations.
