Overview
The UCC21220ADR is a single-channel digital isolator from Texas Instruments, designed for high-reliability industrial and automotive applications. It features a 5 kVrms isolation voltage rating with reinforced insulation characteristics. The device operates with a supply voltage range of 3.0 V to 5.5 V on both the isolated side and the logic side. It supports data rates up to 150 Mbps and includes a common-mode transient immunity of 100 kV/µs. The package is an 8-pin SOIC (DW) with a wide body, providing robust thermal performance and ease of PCB integration.
Feature Summary
- Reinforced dual-channel isolation capability within a single-channel configuration for enhanced safety compliance
- High common-mode transient immunity ensuring reliable signal transmission in noisy environments
- Integrated low-power design supporting efficient operation across varying load conditions
Applications
- Industrial motor drives and inverters
- Power supply feedback loops
- Isolated gate drivers for power semiconductors
Procurement Notes
Verify the suffix 'ADR' indicates tape-and-reel packaging when ordering. Confirm the operating temperature range matches your specific application requirements. Ensure compatibility with the intended logic family voltages. Check for any recent lifecycle status updates or obsolescence notices directly from Texas Instruments documentation before finalizing procurement plans.
Selection Notes
Select this component when reinforced isolation is required for safety-critical systems. Consider the 150 Mbps data rate limit for high-speed communication needs. Evaluate the 8-pin SOIC package constraints against available PCB space. Compare common-mode transient immunity specifications against other isolators if extreme noise environments are present.
Part Context
This part belongs to the UCC2122x family of digital isolators, which emphasizes high reliability and safety standards. It complements other devices in the lineup by offering a balance between speed and isolation voltage. The family is commonly used in applications demanding strict regulatory compliance for electrical isolation.
Replacement Considerations
Direct replacements may include UCC21220D or UCC21220DBVR depending on packaging preferences. Verify pinout compatibility and isolation ratings before substitution. Consult official cross-reference guides for equivalent parts with similar electrical characteristics.
