AXP221s is a highly integrated power system management chip, for single core lithium batteries (lithium ion or lithium polymer) and the application of multi-channel switching power output, can provide a simple and easy to use and flexible configuration of the complete power solutions, fully meet the multi-core processor system for power supply is relatively complex and the requirement of precise control.
AXP221s integrates A efficiency up to 94% of the start - Compatible Flash Charger, charging current of 2.1 A. Support both 21, output power (including large current DCDC 5 road, the highest efficiency up to 95%), contains the voltage/current/temperature monitoring such as multi-channel 12 - Bit ADC. In order to ensure the security and stability of power system, AXP221s also integrated the over/under voltage (OVP/UVP), temperature (OTP) and flow (OCP) composition among protection circuit; E - unique to the Gauge ™ electricity meter system in high precision measurement of greatly reduced the battery parameters testing process at the same time.
AXP221s interface provides a quick, make the system can dynamically adjust the output voltage, and cooperate with the various work modes of application processor system transformation, the maximum extend battery life.
AXP221s wisdom energy balance (Intelligent Power Select, IPS ™) circuit can be in USB and external load ac adapter, lithium batteries, and application system security transparency between the distribution of electric energy, and in the external input Power without battery (or battery discharge/damage) under the condition of application system to work normally.
