5.1.3 Storage and VOUT Control Block
This section describes the storage and VOUT control block of S6AE103A as shown in the following schematic. There are two
storage pins and two VOUT pins. The solar energy charges both a small capacitor (400 µF) and a large capacitor (200 mF).

5.1.3.1 Waveform of Charging and Discharging Operation
The following are the details of the charging operation and waveform.
1. Solar energy is the input.
2. Charging starts VSTORE1.
3. When the VSTORE1 voltage achieves the VOUTH setting voltage (3.24 V), the VOUT1 voltage turns on and charging
starts the surplus energy to VSTORE2.
4. Repeat to charge both VSTORE1 and VSTORE2.
