Overview
The UCC21540ADWK is a dual-channel reinforced isolated gate driver from Texas Instruments, housed in a 16-pin SOIC (DWK) package. It provides 5.7 kVRMS isolation and supports peak output currents of 4 A and 6 A per channel. Key electrical parameters include a maximum propagation delay of 45 ns, rise time of 5 ns, and fall time of 6 ns. The device operates within a temperature range of -40°C to +125°C with a power dissipation of 950 mW.
Feature Summary
- Dual-channel design with programmable deadtime for precise switching control
- Reinforced isolation capability supporting high-voltage SiC MOSFETs and IGBTs
- Opto-compatible input interface for simplified system integration
Applications
- Driving Silicon Carbide (SiC) MOSFETs in high-frequency converters
- Insulated Gate Bipolar Transistor (IGBT) gate driving in industrial inverters
- Isolated power supply feedback loops requiring high common-mode transient immunity
Procurement Notes
Verify the specific suffix 'DWK' corresponds to the 16-lead SOIC package when ordering. Confirm that the 'A' variant meets the required operating temperature and isolation specifications for your application. Ensure compatibility with the host controller logic levels before procurement.
Selection Notes
Select this component when dual-channel isolation with programmable deadtime is required. It is suitable for applications demanding high peak current drive capabilities for wide-bandgap semiconductors. Consider the SOIC-16 footprint constraints and thermal dissipation requirements during PCB layout.
Part Context
This part belongs to the UCC2154x family of reinforced isolated gate drivers. It shares architectural similarities with the UCC21540 and UCC21541 but differs in specific current ratings and package options. The DWK suffix denotes the specific surface-mount package configuration used in this variant.
Replacement Considerations
The UCC21540ADWR serves as a pin-compatible alternative in a different SOIC-16 package variant. Verify package dimensions and thermal characteristics before substitution. No other direct cross-model replacements are confirmed in public documentation.
