Overview
The MIC94305YCS-TR is an integrated load switch from Microchip Technology, featuring Ripple Blocker™ active filter technology. It operates within an input voltage range of 1.8V to 3.6V, designed for true load switching of low-voltage power rails in electronic devices. The component provides a continuous current capacity of 500mA and is housed in a compact 6 UFBGA (WLCSP) package with dimensions of 0.84mm x 1.32mm. It is supplied in Tape & Reel packaging.
Feature Summary
- Incorporates Ripple Blocker™ active filter technology to reduce output noise
- Provides integrated load switching capability for low-voltage power rails
- Supports general-purpose switching applications with single output configuration
Applications
- Low-voltage power rail switching in portable electronics
- Noise-sensitive circuit protection in consumer devices
- Power distribution management in compact embedded systems
Procurement Notes
Verify the specific suffix YCS-TR against official Microchip documentation to confirm package type and tape/reel specifications. Confirm part status as obsolete if sourcing through secondary markets. Ensure compatibility with existing PCB footprint designs utilizing the 6 UFBGA form factor before procurement.
Selection Notes
Select this component when ripple reduction is critical for downstream sensitive loads. The fixed 500mA rating suits moderate current requirements without external pass transistors. Consider the small WLCSP package size for space-constrained layouts where traditional SOT or QFN packages are unsuitable.
Part Context
This device belongs to Microchip's Ripple Blocker series, which integrates filtering capabilities directly into the load switch architecture. It differs from standard switches by actively suppressing input ripple, offering a simplified solution for clean power delivery in battery-operated or noise-prone environments compared to discrete RC filter approaches.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify cross-references with Microchip engineering support for direct pin-compatible alternatives.
