The MPQ4253B integrates a monolithic, step-down switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port. The MPQ4253B can achieve up to 6A of output current (IOUT) across a wide input voltage (VIN) range, with excellent load and line regulation. The USB outputs are fixed as one USB Type-A USB port and one USB Type-C USB port. Each USB switch is current-limited. The USB1 port supports USB Type-C 5V @ 3A DFP mode. The USB2 port supports DCP schemes for battery charging specification (BC1.2), Apple divider 3 mode, and 1.2V/1.2V mode, which eliminates the need for outside user interaction. The MPQ4253B buck and USB2 output are always on if EN is high. If USB2 detects that a device is plugged in, then the USB1 port capability changes to 1.5A automatically. The step-down converter uses peak current (IPEAK) mode control to regulate IOUT. Under light-load conditions, the part enters pulse-frequency modulation (PFM) mode to improve efficiency. Full protection features include over-current protection (OCP) with hiccup mode, output over-voltage protection (OVP), and thermal shutdown. The device supports load-shedding mode for the USB1 port. When entering load-shedding, the USB Type-C advertised current capability changes to 1.5A. The MPQ4253B requires a minimal number of readily available, standard external components, and is available in a QFN-26 (5mmx5mm) package.
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.
MPQ4253BGU-AEC1 is an authentic electronic component manufactured by Monolithic Power Systems, 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 MPQ4253BGU-AEC1 datasheet above.
Electronic component spot-market pricing for MPQ4253BGU-AEC1 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.
Lead times for MPQ4253BGU-AEC1 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.
