To Realize More Features, Longer Operating Time and Smaller Size

Smartwatch, which is large and charge is frequently required, is not smart? Designing the power supply circuit of mobile devices for wearable applications, such as smartwatch, is to solve many technical problems to realize the customers’ high expectations. Reduction of the current consumption and the frequency of battery charging can be realized by using advanced and high-performance power management ICs. In addition to these power management ICs is contributing to the evolution of mobile devices by providing operational amplifiers for amplifying sensor signals, a key feature of mobile devices, as well as high-performance and small size package discrete products such as MOSFETs, TVS diodes (ESD protection diodes), SBDs, and transistors.

Features

• Support to design of power supply circuit with abundant line-up of power management ICs to meet many requirements
• Reduced current consumption of power management ICs to reduce battery charging frequency
• Miniaturization of packages ideal for mobile devices to reduce power supply circuit space
• Compliance with New Safety Standard (IEC-62368-1) (eFuse IC)
• Useful application notes, reference designs, and other documents on the web save design cycle time

Power Management

In the design of the charging circuit, not only the realization of reliable control, whether for wireless charging or charging with a cable, but also the protection of the circuit from unexpected short-circuits of the power supply, external noise such as EMI, and other abnormal conditions are required.

For power management in the later stage circuit from PMIC of integrated power supply ICs, modules such as sensitive sensors and chipsets may have higher performance requirements for power supply. The LDO regulators and load switch ICs deliver high performance with minimal current consumption and are packaged in small wafer-level chip-scale packages.
