BPS 50–90A Smart DrMOS, an Innovative Breakthrough!

Driven by the rapid development of cutting-edge applications such as 5G, AI (Artificial Intelligence), the metaverse, cloud computing and autonomous driving, the market’s demand for computing power from core processors (such as CPUs, GPUs, DPUs, ASICs, etc.) continues to soar. These main chips also pose unprecedentedly stringent challenges for their power supply.

BPS has launched the Smart DrMOS intelligent integrated power device chip, achieving key breakthroughs in the field of high-efficiency, high-density and intelligent power management. With its core advantages such as fully integrated design, excellent performance and low quiescent power consumption, it has significantly improved efficiency of system and created an efficient and reliable power management for core processors.

The BPS DrMOS adopts self-developed large-current packaging, including frame & stacked packaging, and uses single-crystal process BCD technology. The fully integrated design achieves simplicity, and packaging forms of different specifications can be adapted to different categories.

The BPS DrMOS is widely applicable to operating conditions with an input voltage of 3V-24V and a load of 50A-90A, with a working frequency of up to 1.5MHz. It can meet the power supply requirements of high-wattage, high-efficiency, and high-power-density chips, achieve high-frequency miniaturized power supply solutions, and deliver excellent performance in thermal management and EMI (Electromagnetic Interference) suppression.

The chip integrates a current detection circuit with a gain of 5μA/A or 10μA/A, delivering excellent current sampling accuracy and transient response performance. Meanwhile, an on-chip temperature detection circuit provides real-time junction temperature monitoring and protection alarms. These two functions quickly and accurately transmit power-stage current and temperature data, enabling fast interconnection with the processor load and precise closed-loop regulation of processor power.

The BPS DrMOS supports comprehensive protection functions, including Over-Temperature Protection (OTP), Over-Current Protection (OCP), High-side MOSFET Short Protection, and Under-Voltage Lockout (UVLO), ensuring the operational safety of the entire power supply system.

For mobile electronic devices such as laptops, BPS provides compatible DrMOS product series with a quiescent current of only 100μA. The low quiescent current significantly reduces the system power consumption of mobile devices in standby mode, thereby extending battery life. Meanwhile, it maintains the instantaneous fast response capability of the power stage, which means the DrMOS can quickly adapt to changes in the operating state of electronic products, bringing users an excellent experience.

In addition to the Smart DrMOS product series, BPS has launched a complete set of power supply solutions for domestic and international markets: multi-phase digital controllers, integrated synchronous buck converters, electronic switch/thermal plug control products, etc., providing one-stop service for our customers.
