Overview
The UCC21521ADWR is a dual-channel reinforced isolated gate driver manufactured by Texas Instruments. It provides a peak source current of 4A and a peak sink current of 6A, designed for driving power MOSFETs and IGBTs. The device features a maximum propagation delay of 30 ns and operates within a temperature range of -40°C to +125°C. It utilizes a 16-SOIC surface-mount package and supports an operating supply voltage range of 6.5V to 25V. The isolation rating is 5.7kVRMS.
Feature Summary
- Dual-channel architecture with independent enable controls for each channel
- Programmable deadtime functionality to prevent shoot-through in half-bridge configurations
- Reinforced galvanic isolation capability ensuring high safety standards
- High peak output current drive strength for efficient switching of power devices
Applications
- Industrial motor drives and inverters
- Solar micro-inverter systems
- Uninterruptible power supplies (UPS)
- Switched-mode power supplies (SMPS)
Procurement Notes
Verify the complete part number including the 'ADWR' suffix to ensure correct packaging and tape-and-reel configuration. Confirm RoHS compliance status and humidity sensitivity level prior to assembly. Cross-reference the datasheet revision date to ensure compatibility with latest design guidelines. Validate that the SOIC-16 footprint matches the intended PCB layout requirements.
Selection Notes
Select this component when high-speed switching with precise deadtime control is required in isolated environments. The 4A/6A current capability suits medium-power applications. Consider the 5.7kVRMS isolation rating for safety-critical designs. Ensure the input logic levels are compatible with the controller MCU. Evaluate thermal performance within the specified -40°C to +125°C operating range.
Part Context
This device belongs to the UCC2152x series of isolated gate drivers from Texas Instruments. It shares architectural similarities with the UCC21520 but includes additional programmable deadtime features. The ADWR designation indicates a specific reel-based packaging format suitable for automated surface-mount assembly processes in high-volume manufacturing environments.
Replacement Considerations
The UCC21520ADWR is a related variant lacking programmable deadtime. Verify functional equivalence if substituting. Check pinout compatibility and isolation ratings before replacing with other TI isolated drivers.
