Wearable PMIC Enables Voltage Scaling

The tech company, established in 2022, has received seed funding from Zepp Inc., a renowned provider of digital health and well-being software and systems. This strategic partnership positions the startup, known as Orca, to customize its offerings and compete effectively with industry giants in the analog devices sector.

One of Orca's flagship products is the OS1000, a Power Management Integrated Circuit (PMIC) specifically designed for health wearables, hearables, and various connected devices like smartwatches. This innovative device features a linear lithium-ion battery charge management block and two low quiescent current, low drop-out regulators that facilitate dynamic voltage scaling (DVS).

Moreover, the buck converters integrated into the OS1000 support microcontroller operations with the ability to handle up to four DVS voltage levels. These levels can be controlled through dedicated pins for swift voltage transitions or via I2C communication, enhancing the device's flexibility and efficiency.

In addition to its core functionalities, the OS1000 offers essential system support features required in diverse applications. These include a power supply startup sequencer and a low current off or shelf-mode that reduces current draw to less than 100nA, ensuring optimal performance and energy efficiency.

Measuring a compact 2.4mm by 2.0mm, the OS1000 comes in a 30-bump WCSLP package with a 6 by 5 bump array arranged on a 0.4mm pitch. Andrew Baker, the CEO of Orca, emphasized the company's dedication to providing top-notch customer service and tailored analog products that accelerate the time-to-market for innovative solutions in smart health and smart factory domains.
