AXP209
Enhanced single Cell Li-Battery and Power System Management IC
9.7 Signal Acquisition System
Simple battery monitors estimate the battery energy by measuring the battery voltage. However, the
multiple 12-bit ADCs in the AXP209 can measure battery voltage, as well as battery current and
external power voltage and current. It integrates battery charge and discharge coulomb counter. Using
this data, the Host is capable of calculating accurately the battery energy and other battery data, such
as the system real-time consumption, remaining battery energy, battery charge progress, remaining
battery using time and charge time, etc.
The enabled state and sampling rate of each ADC can be set via registers REG82H, 83H, 84H. The
sampling results will be saved in corresponding registers, and reference can be made to the
ADC data in Register Instruction section. The input range of GPIO[1:0] can be set via register
REG85H, while register REG00H[2] is used to indicate the battery charge/discharge current directions.

GPIO [3: 0]
GPIO[3:0] Can be defined as ADC Input (monitoring external signals), or LDO, etc. Please refer to
REG90H-96H Instruction for details.
CHGLED
Features charge state indication, over-temperature/over-voltage warning, and GPO. Please refer to
REG32H Instruction section for details.
9.9 Timer
AXP209 Contains a 7 bit Internal timer, the value is set by register REG8AH [6: 0]. If the register is set to 0,
the timer is disabled. If REG8AH [6: 0] = A, The timer starts count from 0 to A and sets REG8AH [7], also
