DESCRIPTION

AXP288 is a highly integrated PMIC targeting at 1- cell
Li-battery (Li-ion or Li-polymer)
applications,customized for Intel Cherry Trail-T3 SoC. It
provides an easy and flexible battery management
solution for large current charge and system power
supply. AXP288 comes with a 5v input Charger that supports
up to 2.8A charge current. To ensure the security and
stability of the power system, AXP288 provides
multiple channels 12-bit ADC for
voltage/current/temperature monitor and integrates
protection circuits such as OVP, UVP, OTP, and OCP. Moreover, AXP288 features a unique E- Gauge™(Fuel Gauge) system, making power gauge
easy and exact.

In addition, AXP288 embraces a fast interface for
the system to dynamically adjust charge current
and power rail output voltage so that the battery
charge time could be saved and battery life
can be extended to the largest extent. Besides, AXP288 features an IPS™ (Intelligent Power
Select) circuit to transparently select power path
among adapter and Li-battery to system load. AXP288 is available in 9mm x 9mm 76-pin QFN
package, and the package is Pb free
