Axp209 Circuito Administrador De Energia Qfn48 Itytarg

AXP209 is designed to be a highly-integrated power system management IC that is optimized for applications requiring single-cell Li-battery (Li-Ion/Polymer) and multiple output DC-DC converters. It is offering an easy-to-use and flexible complete solution which can fully meet the increasingly complexity of accurate power control required by modern application processor system. AXP209 Incorporates an adaptive USB-Compatible PWM Charger, 2 Buck DC-DC converters,5 Linear regulators (LDOs), Voltage/Current/Temperature and other multi-channel 12-Bit ADC, as well as 4 Configurable GPIOs. To ensure power system safety and stability, the AXP209 also integrates over/under (OVP / UVP), Over temperature(OTP), and Overcurrent (OCP) Protection circuits. With Intelligent Power Select, IPS™ circuits, the AXP209 can distribute power safely and transparently among external AC-adapter, Li-battery and application system load. It can still work normally when there is no battery (e.g. deeply discharged/defective battery) but only external input power source. The AXP209 provides a small, simple solution for obtaining power from three different power sources; single-cell Li-Ion battery, USB port, and AC-adapter. It can also support a rechargeable backup battery too. To ensure compatibility with a wide range of system processors, AXP209 uses a Two Wire Serial Interface (TWSI), through which application processor is capable of enabling/disabling power rails, programming voltages, accessing internal registers, as well as measurement data (including Fuel Gauge). With the power monitoring results of high precision (1%, determined by the 1% BIAS resistance), end users will always know the real-time power consumption, which can bring them an unprecedented experience of power management. AXP209 Provided 6mm x 6mm 48-pin QFN Package.
