[Outline]
This IC is a Mitsumi has developed an IC that monitors 3 power supplies constituted by an AC adaptor, the USB port, and lithium ion secondary battery and controls the system drive power supply and the charging.
The charging control is adapted to the battery temperature profile.
The IC is equipped with safe and highly efficient switch mode charging control to realize optimal power management for the mobile device.

[Features]
1. 
Built-in power switch for switching between AC adaptor/USB, and built-in charging control function.
The IC controls the power supply from the AC adaptor, USB and lithium ion secondary battery.
2. 
The power supply is controlled to fit the charging temperature profile for safe and highly efficient charging.
Thanks to control using I2C, the charging temperature profile can be altered.
3. 
The switch mode charge control format allows a large charging current (Max 2A) to be supported.
The I2C control also allows changes to be made in 100 mA steps.
