USB power controller in a standard SOIC-8 footprint
The MIC2012PZMTR from Microchip Technology is a USB power controller that manages power delivery on a USB port. It operates from a 4.5V to 5.5V supply and draws only 22 µA quiescent current, making it suitable for always-on USB hubs or battery-powered equipment where every microamp matters. The 8-SOIC package (0.154", 3.90mm width) is a widely used surface-mount footprint that reflows easily and fits on two-layer boards without tight fan-out constraints.
Supply range and temperature grade set the application boundary
The 4.5V–5.5V supply range ties the controller directly to a 5V USB bus rail; a 3.3V-only system cannot use this part without a boost regulator. The commercial temperature grade of 0°C to 70°C restricts the part to indoor, climate-controlled environments — no outdoor or under-hood USB ports. At 22 µA supply current, the quiescent loss is negligible — less than 0.1% of a 500 mA USB port budget — so the controller does not eat into the downstream device's current allowance.
Active lifecycle and sourcing posture
Sourced to order against your BOM quantity; current pricing and lead time confirmed at quote time. The 8-SOIC package is widely stocked across the distribution channel, but availability varies by date code and region — an RFQ locks the best available lot.
