GENERAL DESCRIPTION
The ACT5880 provides total 15 power rails and
manages them through an I
2
C compatible serial
interface, together with the CCCV charging battery
management, builds a nearly complete environment
for running smart phone system, mobile internet
device system, or any system with rich peripherals
like wireless modules, various radio recievers.
The CCCV charger in the ACT5880 is a full function
super set for safe operation in various system
conditions, including charging without system
involving, charging with heavy system load and
charging in long cord-time operation.
Other benefitial functions inlcude a touch-screen
controller, 3 current controlled LED drivers, one of
which could work with 40V LED string, a RTC and a
backup battery charger.
The ACT5880 is flexible to support different power
on sequences and default power-on states, including
on or off and voltages, which makes it suitable for
various systems with different processors.
The ACT5880 is avialable in 81 balls, 6mmX6mm in
size, 1mm in height FC FBGA package.
