XP288AXP288 is customized PMIC for Intel Baytrail (BYT-CR) and Cherrytrail (CHT-CR) platforms. AXP288 is a highly integrated PMIC targeting at Li-battery (Li-ion or Li-polymer) applications that require multi-channel power conversion outputs. It provides an easy and flexible power management solution for processors to meet the increasingly complex and accurate requirements on power control. AXP288 comes with an adaptive USB3.0-compatible Flash Charger that supports up to 2.8A charge current. It also supports 20 channels power outputs (including 6-CH Bucks). 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 output voltage and enable power outputsso that the battery life can be extended to the largest extent. Besides, AXP288 features an IPS™ (Intelligent Power Select) circuit to transparently select power path among USBand Li-batteryto system load. AXP288 is available in 9mm x 9mm 76-pin QFN package, and the package is Pb free.
