Orca Semiconductor Inc. (Milpitas, Calif.), a startup formed to offer analog and mixed-signal circuits, has launched its first product a PMIC for wearables and hearables.

The company, founded in 2022, is seed funded by Zepp Inc., a provider of digital health and well-being software and systems (see Startup Orca will customize to compete with ‘Big Analog’).

The OS1000 is a PMIC developed for health wearables, hearables and other connected devices such as smartwatches.

This device contains a linear lithium-ion battery charge management block and two low quiescent current, low drop-out regulators that support dynamic voltage scaling (DVS).

The buck converters support microcontroller operation with up to four DVS voltage levels controlled through dedicated pins to rapidly transition between voltages or via I2C communication.

The OS1000 also offers system support functions required in applications including a power supply startup sequencer and a low current off or shelf-mode that drops current draw below 100nA.

The part comes in a 30-bump WCSLP package that measures 2.4mm by 2.0mm. The 6 by 5 bump array is arranged on a 0.4mm pitch.

“We are committed to delivering industry leading customer service and customized analog products that will speed time to market for innovative smart health and smart factory solutions,” said Andrew Baker, CEO of Orca, in a statement.
