Key Features
- P-channel MOSFET rated 1.8 A continuous and 6 V VDS for low-voltage load switch and power rail control
- Ultra-compact 4-pin SOT-143 package enabling minimal footprint power switching in portable and wearable designs
- Tape-and-reel (TR) packaging for high-volume automated SMT assembly in handheld device production
Applications
MIC94050YM4 TR is used as a low-side or high-side P-channel load switch in battery-powered portable electronics, IoT devices, and wearable products requiring controlled power delivery. Its 6 V rating and 1.8 A current capacity suit applications such as Li-ion battery protection, USB power switching, and peripheral enable circuits. The SOT-143 package keeps the power switching footprint below 2 mm x 1.5 mm, ideal for compact PCB designs with tight space budgets.

Frequently Asked Questions
What are the key electrical ratings of MIC94050YM4 TR for a 5 V USB load switch design?
MIC94050YM4 TR is rated for a maximum 6 V drain-to-source voltage and 1.8 A continuous drain current, making it directly suitable for 5 V USB power switching where load currents stay below 1.8 A. The P-channel topology allows high-side switch configurations without a charge pump, simplifying gate drive circuits in USB peripheral enable stages.
How does the SOT-143 package of MIC94050YM4 TR benefit space-constrained wearable designs?
The 4-pin SOT-143 package of MIC94050YM4 TR has a footprint of approximately 2.9 mm x 1.3 mm, occupying far less PCB area than larger SOT-23 or SOIC alternatives for the same 1.8 A / 6 V P-channel MOSFET function. This miniature package is well-matched to wearable sensors, hearing aids, and compact IoT nodes where every square millimeter matters.
Is MIC94050YM4 TR available in tape-and-reel format, and how does that support high-volume production?
MIC94050YM4 TR ships in tape-and-reel (TR) format, compatible with standard pick-and-place SMT assembly equipment for production volumes requiring thousands of units. The reel format reduces manual handling errors and supports continuous-feed assembly lines producing battery-powered handheld devices at 1.8 A / 6 V P-channel load switch positions.
