Procurement Notes
Verify the ACT3780QY-T status as discontinued through official Qorvo channels or authorized distributors before procurement planning. Confirm RoHS compliance documentation and request the specific datasheet for accurate electrical characterization. Ensure compatibility with existing system voltage requirements ranging from 4.35 V to 12 V input. Validate moisture sensitivity handling procedures during assembly to prevent package damage.
Selection Notes
Select this component for applications requiring a specialized single-cell lithium-ion charging solution with low quiescent current. Consider the 4.35 V to 12 V input range when designing power supply rails. Evaluate the moisture sensitivity classification for appropriate storage and reflow soldering profiles. Compare against active alternatives if long-term availability is critical for the product lifecycle.
Part Context
Qorvo, formerly TriQuint Semiconductor, manufactures this part as part of its power management portfolio. The company specializes in RF front ends, power amplifiers, and semiconductor solutions for automotive, industrial, and mobile markets. The ACT3780QY-T represents their approach to integrated battery management for portable devices.
Replacement Considerations
The ACT3780QY-T is listed as discontinued. Engineers must identify equivalent single-cell lithium-ion chargers from current Qorvo lines or other manufacturers. Verify pin compatibility, input voltage ranges, and charging algorithms when selecting a substitute component.
