3. TECHNICAL BRIEF
- If AD6720 detects that Charger is inserted, the CC-CV charging starts.
- Exception : When battery voltage is lower than 3.2V, the precharge
(low current charge mode) starts firstly.
- And the battery voltage reach to 3.2V the CC-CV charging starts.
3. Pins used for charging
- VCHG : charger supply.
- GATEDRIVE : charge DAC output
- ISENSE : charge current sense input
- VBATSENSE : battery voltage sense input.
- BATTYPE : battery type identification input
- REFCHG : voltage reference output
4. TA (Travel Adaptor)
- Input voltage: AC 85V ~ 260V, 50~60Hz
- Output voltage: DC 5.2V ( 0.2 V )
- Output current: Max 800mA ( 50mA )
5. Battery
- Li-ion battery (Max 4.2V, Nom 3.7V)
- Standard battery: Capacity - 830mAh
