New AXP209 Enhanced single Cell Li-Battery and Power System Management IC

AXP209 chip is a highly integrated power system management, 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 a complete power solutions, fully meet the increasingly complex application processor system for power supply requirements of precise control. AXP209 integrates a adaptive USB - Compatible PWM chargers, two-way step-down converter (Buck DC - DC converter), 5 line voltage stabilizer (they), voltage/current/temperature multi-channel 12 - Bit ADC, and configurable GPIO 4 road. In order to ensure the security and stability of power system, AXP209 also integrated the over/under voltage (OVP/UVP), temperature (OTP), such as flow (OCP) composition among protection circuit. AXP209 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. AXP209 have external adapter and USB and battery input ability, support the rechargeable battery back-up. AXP209 provides a two-wire Serial communication Interface: Two Wire Serial Interface (TWSI), application processor can use this Interface to open or close some output power, voltage, set them access to the internal registers and a variety of measurement data (including arg, the Gauge). High precision (1%, mainly is decided by 1% accuracy of BIAS resistors) of electricity measurement data real time control of the electricity usage convenient consumers more clear, bring the unprecedented equipment electricity use experience to consumers.
