Voltage Description
Level
0~3.3V Low Active, system suspend control signal
0~floating Low Active, POWER ON control signal.
High Active, ENE926 use this pin to control the fast charge of
0~3.3V
charge
High Active, turn off the Adaptor power for battery automatic
0~3.3V
learning cycle
High Active, provide to ENE926 to mean the Adaptor power is
0~3.3V
present
0~3.3V High Active, it will go high when +CPU_CORE is ready
0~3.3V High Active, turn on/off the +CPU_COREP & VID_VCC
Analog signal, ENE926 using this voltage level to calculate
0~3.3V
battery's temperature
Analog signal, ENE926 using this voltage for setting charge
0~3.3V
current
0~3.3V The +CPU_CORE voltage depends on those PIN's VID [6..0]
3.3V Charge RTC-battery power source
Interface of Smbus, communicate between ENE926 and smart
0~5V
battery
0~3.3V High Active, ENE926 use this pin to control the SYSON signal
Analog signal, ENE926 using this voltage level for battery over
0~3.3V
voltage protection
0~1.05V Analog signal, enable CPU_CORE regulator at light load mode.
0~1.05V Analog signal; control CPU C3, C4 signal.
