Product Details
Key Features

The MIC1344 is an advanced two input, one output, hot swappable, power multiplexer. It has both automatic and manual input selection (ENA and ENB) and four status outputs.

In automatic mode, the MIC1344 will automatically connect the higher of two input voltages (INA or INB), to the output (OUT). In manual mode, either of the two inputs can be routed to the output, or both power inputs can be turned off so that multiple MIC1344s can be used for more than two power inputs.

The MIC1344 has four digital open drain status outputs. The ASEL\ and BSEL\ outputs indicate which input is selected. The STAOK and STBOK outputs indicate the general health of the input channels. Specifically, these outputs will be inactive (high) if the channel has sufficient input voltage, the channel current is within acceptable limits, the die temperature is not too hot, and the channel has no reverse current detected.

The current limit for each input channel of the MIC1344 can be individually set up to 3A, by two external current-limit set resistors (ILIMA and ILMIB). The current flowing in each of the channels can be read by measuring the voltage at these resistors.

YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.

  • 1. Certification Scope: Quality certifications apply only to the entities, sites and activities listed in valid certificates. Management system certification does not certify each individual product.
  • 2. Product Authenticity: Products must match the agreed manufacturer, part number and condition. Supplier screening and authenticity checks help reduce counterfeit risk.
  • 3. Inspection & Testing: The inspection scope follows product risks and agreed requirements. Additional testing, laboratory arrangements, costs and lead times require written confirmation.
  • 4. Traceability & Documentation: Request conformity certificates, traceability records or test reports before ordering. Document availability, issuer and coverage must be confirmed for the offered goods.
  • 5. Environmental Compliance: RoHS and REACH information is based on applicable manufacturer documentation. Confirm the exact part, declaration date and relevant exemptions before ordering.
  • 6. Handling & Protection: Handling, storage and packaging follow applicable product requirements, including ESD and moisture protection where required. Special handling requirements must be agreed before ordering.

Product FAQ
Purchasing FAQ

What type of component is MIC1344, and what package does it use?

MIC1344 is an authentic electronic component manufactured by Microchip, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MIC1344 datasheet above.

Why is pricing for MIC1344 available via RFQ rather than a fixed checkout price?

Electronic component spot-market pricing for MIC1344 fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.

How quickly can MIC1344 be shipped once quoted?

Lead times for MIC1344 depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
