Recently, MPS Xinyuan System (NASDAQ code: MPWR) officially released the industry's first automotive grade fully integrated electronic fuse (eFuse) for 48V systems - MPQ5884. With the advantages of high integration, comprehensive protection, and intelligent reliability, it helps optimize the spatial layout of the entire vehicle design and further achieve cost reduction and efficiency improvement.

At present, the 48V system is becoming the core of the next generation of automotive electronic and electrical architecture. It not only supports higher power loads, reduces the quality of the vehicle's wiring harness, but also provides a stable power supply foundation for advanced driver assistance (ADAS), in car interconnection, electronic control and other systems. Electronic fuses, as a key component of vehicle architecture circuit protection, are widely used in automotive domain controllers and distribution boxes to provide more advanced protection for wiring harnesses and loads.

The electronic fuse product MPQ5884 launched by MPS can cover a wide voltage output range of 6-60V, supporting a maximum load rejection of 80V and a minimum reverse withstand voltage of -60V. The rated current covers applications from 7A to 25A. The chip supports low-power mode, in which the static current is only 25uA, and it can automatically switch back to normal mode when the load suddenly changes, avoiding output power failure.

Highly integrated functionality, building system security barriers

MPQ5884 integrates multiple diagnostic and powerful protection functions to improve system performance and stability. In addition to the configurable I2T overcurrent protection, input anti negative protection, reverse current protection, open circuit diagnosis, and ground loss protection can be achieved without the need for other external circuits, and load current information and chip temperature can also be read in real time.
Optimize spatial layout with smaller packaging

As the industry's first fully integrated 48V system electronic fuse, MPQ5884 adopts QFN-30 (5mmx6mm) packaging, achieving a more compact and efficient design. Compared with the current mainstream controller solutions, this packaging can greatly reduce the board area and further save material costs.

Widely applicable scenarios, supporting functional safety system design

Designed specifically to meet stringent automotive transient immunity standards such as ISO 7637-2/16750-2/21780, the MPQ5884 has not only passed AEC-Q100 Grade 1 certification, meeting the highest reliability standards of automotive regulations, but also offers MPSafe ™ Functional safety support documents to assist in the design of ASIL level systems.
In practical applications, it can be applied to various high demand automotive electronic scenarios as follows:
Fuse and relay replacement: improving overcurrent protection accuracy and extending lifespan
48V system driver module: such as motor, heater, water pump, etc
Power Distribution Unit (PDU) and Battery Management System (BMS)
Control of resistive, capacitive, and inductive load switches

Product purchase and technical support

In addition to MPQ5884, MPS will also gradually launch the MPQ588X series products, covering the current range of 7A-25A. The 7A-15A products are compatible with each other in QFN (5mmx6mm) packaging, while the 25A is in QFN (6mmx8mm) packaging. At present, MPQ5884 has officially entered mass production and can be purchased directly on the MPS official website. In addition, samples can also be provided for other products in the series.
