Overview
The UCC21220DR is a dual-channel galvanically isolated gate driver from Texas Instruments, housed in a 16-pin SOIC package. It provides 3 kVrms isolation voltage and supports input logic levels of CMOS or TTL with a supply range of 3 V to 5.5 V. The device delivers peak output currents of 4 A and 6 A for high-side and low-side driving respectively. Key electrical parameters include a maximum propagation delay of 45 ns, rise and fall times of 8 ns, and a power dissipation rating of 950 mW. It operates within a temperature range of -40°C to +125°C and includes a shutdown function.
Feature Summary
- Provides galvanic isolation between input and output circuits to protect control side components.
- Features independent high-side and low-side channels for bridge configurations.
- Includes a dedicated shutdown pin for disabling outputs.
Applications
- Industrial motor drives
- Inverter systems
- Solar microinverters
Procurement Notes
Verify the specific suffix 'DR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 16-pin SOIC footprint matches the target PCB layout dimensions. Ensure compatibility with the system's voltage domains and thermal management requirements before finalizing procurement.
Selection Notes
Select this component when dual-channel isolation with moderate speed (45 ns delay) is required. It is suitable for applications needing 3 kVrms isolation without the complexity of advanced protection features found in higher-tier drivers. Consider the SOIC-16 package constraints and the 950 mW power dissipation limit during thermal design.
Part Context
This part belongs to the UCC21220A series of basic isolated gate drivers. It serves as a fundamental solution for bridging low-voltage control logic with high-power switching devices. The DR suffix indicates reel packaging, distinguishing it from tube-packaged variants like the AD.
Replacement Considerations
The UCC21220ADR is a direct functional equivalent with identical specifications but differs in packaging type. Verify if the manufacturing facility requires reel or tube formats for production lines.
