Part Status
Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

Description
The ACT8810 is an eight-channel ActivePath™ power management IC that integrates a complete battery charging and management system with six power supply channels. The ActivePath architecture automatically selects the best available input supply for the system and provides additional current from the battery if needed. The charger is a complete, thermally-regulated, stand-alone single-cell linear Li charger that incorporates an internal power MOSFET.
The six power supply channels include three independent, fixed-frequency, current-mode step-down DC/DC converters (REG1, REG2, and REG3) that output 1.3A, 1.0A, and 0.55A, respectively. There are also two high-performance, low-noise, low-dropout linear regulators (REG4 and REG5) that output up to 360mA each. Finally, there is a RTC LDO (REG6) that outputs up to 30mA for a real-time clock.
The ACT8810 is available in a tiny 5mm x 5mm 40-pin Thin-QFN package that is just 0.75mm thin.
