I. MPS USB Switches: Precise Current Control, Efficient Switching

USB switches are the core control components for the power path in USB interfaces. They are primarily used to enable intelligent switching, precise current limiting and load isolation in USB power supply circuits, effectively preventing circuit faults caused by device insertion/removal or abnormal loads. They are the fundamental core components of the USB interface power chain. MPS USB switches utilise a proprietary low on-resistance process, combining low loss, high responsiveness and compact design, making them suitable for a wide range of high- and low-power USB power supply scenarios.

Key Product Features:

- Ultra-low on-state loss: The entire range of switch devices features extremely low on-state resistance, significantly reducing heat generation and power loss during power supply, thereby enhancing the overall power supply efficiency of the system and making them suitable for prolonged continuous operation;

- Precise and controllable current limiting: Supports adjustable output current limiting, allowing the operating current to be configured according to device requirements, thereby preventing circuit damage caused by load overcurrent or short circuits;

- High-speed on/off response: Features rapid switching response times, making it suitable for high-frequency plugging and unplugging, as well as dynamic load switching scenarios, thereby preventing damage to end devices caused by transient voltage fluctuations;

- Minimal peripheral design: Requires no complex peripheral circuits; assembly can be completed with just a few standard components, significantly simplifying PCB layout and saving space within the device.

Typical Applications: USB ports in consumer electronics, auxiliary power supply interfaces in vehicles, portable charging devices, and industrial small-load switches, amongst other scenarios.

II. MPS USB Controllers: Full Protocol Compatibility, Intelligent Management

MPS USB controllers serve as the ‘intelligent hub’ for USB interfaces, focusing on charging protocol parsing, power negotiation and port mode management. They are fully compatible with mainstream USB charging and power delivery protocols, covering both traditional fast-charging protocols and the next-generation USB PD high-voltage fast-charging standard. They are categorised into two main product lines: general-purpose fast-charging controllers and high-end PD smart controllers, covering both consumer-grade and automotive-grade application scenarios.

Key representative models and technical advantages:

- MP5034 General-Purpose Fast Charging Controller: Supports mainstream fast-charging protocols such as BC1.2, DCP, frequency-division mode and QC3.0; automatically identifies the charging requirements of terminal devices without manual intervention and adaptively matches the charging power; integrates basic protection functions such as input overvoltage protection and over-temperature shutdown; requires minimal peripheral components and is suitable for the design of small-to-medium-power fast-charging devices.

- MPF52001 High-End USB PD Controller: Integrates a 32-bit ARM Cortex-M0 core with a maximum clock speed of 36 MHz; supports the USB PD 3.1 standard and PPS (Programmable Power Supply) mode, suitable for high-power fast charging up to 100 W; supports firmware upgrades and CC-pin protocol management, enabling intelligent power allocation across ports, and is suitable for high-power Type-C power delivery devices.

- MPQ5029 automotive-grade port controller: AEC-Q100 certified, integrating a USB current-limiting switch and port identification circuitry; supports 3A continuous high-current output; suitable for in-vehicle Type-C charging ports; compatible with the full range of in-vehicle charging protocols; resistant to high temperatures and interference; suitable for complex in-vehicle operating conditions.

Key advantages: comprehensive protocol coverage, power adaptability, support for intelligent firmware updates, and dual automotive/consumer-grade specifications, meeting all-scenario control requirements ranging from low-power standard charging to high-power PD fast charging at hundreds of watts.

III. MPS USB Protector: All-round protection, building a robust safety barrier

Frequent plugging and unplugging of USB ports, noise from external devices, line surges and electrostatic interference can easily cause damage to ports and main control chips. The MPS USB Protector is specifically designed for USB port safety protection, integrating multiple protection functions such as overvoltage, overcurrent, electrostatic discharge, short-circuit and overheat protection. It is a core protective component for enhancing device stability and extending product lifespan, particularly suited to harsh operating environments such as automotive and industrial applications.

Flagship model: MP4501 (highly integrated USB Type-C protector):

- Ultra-high voltage protection: Supports 60V VBUS short-circuit overvoltage protection and is compatible with the 48V high-voltage operating scenarios of the USB PD EPR extended power mode, covering high-voltage fast-charging protection requirements;

- Professional ESD protection: Integrates IEC-standard ESD protection to withstand electrostatic discharges caused by device insertion/removal and environmental interference, safeguarding downstream control and transmission circuits;

- Integrated multi-functional design: A single chip integrates multiple protection functions—overvoltage, short-circuit, ESD and overheating—eliminating the need for additional protection circuits and enabling a minimalist hardware design;

- High compatibility: Supports all USB Type-C interface specifications, compatible with both standard charging and high-voltage PD fast-charging scenarios, suitable for consumer electronics, in-vehicle devices and industrial terminals.

Core value: Provides a one-stop solution for various electrical anomalies in USB interfaces, significantly reducing device return rates and offering a comprehensive safety barrier for the entire device circuitry.

IV. MPS USB Charging Port: Fully Integrated Solution, Plug-and-Play Fast Charging

The MPS USB charging port is a fully integrated fast-charging solution that combines a high-precision DC/DC step-down converter, intelligent switching transistors, protocol recognition circuitry and protection modules. With no need for multiple peripheral chips, a single module can achieve stable fast-charging output via the USB interface. Available in two main series—consumer-grade and automotive-grade—it supports single-port and dual-port configurations in multiple specifications, making it the optimal solution for lightweight, highly reliable USB charging interfaces.

Key Product Features:

- Full protocol compatibility: Comprehensive support for common charging protocols including USB Type-C (15W), BC1.2, DCP, CDP, QC and Huawei FCP, catering to the charging requirements of various devices such as mobile phones, tablets, in-vehicle terminals and portable devices;
