На ножке 10 микросхемы BQ24726 3.3 В. Судя по даташиту там должно быть порядка 4. ACOK Ножка 3.3 В. Куда еще копать.....
Из даташита...
Необходимые условия для начала зарядки:
In Charge mode, the following conditions have to be valid to start charge:
• Charge is enabled via SMBus (ChargeOption() bit [0]=0, default is 0, charge enabled);
• ILIM pin voltage higher than 105mV;
• All three regulation limit DACs have valid value programmed;
• ACOK is valid (See the Adapter Detect and ACOK Output section for details);
• RBFET turns on and gate voltage is high enough (See "RBFET Turn on and of" for details);
• VSRN does not exceed BATOVP threshold;
• IC Temperature doesn’t exceed TSHUT threshold;
• Not in ACOC condition (See the Input Over Current Protection (ACOC) section for details);
При наличии хотя бы одного условия зарядка будет остановлена:
One of the following conditions will stop on-going charging:
• Charge is inhibited via SMBus (ChargeOption() bit[0]=1);
• ILIM pin voltage lower than 75mV;
• One of three regulation limit DACs is set to 0 or out of range;
• ACOK is pulled low (See the Adapter Detect and ACOK Output section for details);
• RBFET gate voltage is not high enough (See the RBFET Turn on and off section for details);
• VSRN exceeds BATOVP threshold;
• TSHUT IC temperature threshold is reached ;
• ACOC is detected (See the Input Over Current Protection (ACOC) section for details);
