Battery Input Operation
The Solar BLE Sensor has an extra test pad for primary battery input as shown in the following figure. It can connect a primary
battery (not included in the kit) such as a 3-V coin type using test pads. Use soldering to connect the battery to check the solar
and battery operation.
The following is the sample waveform. Note that this sample waveform is for the power gating operation mode of S6AE103A
is in an
“Energy Driven Mode”. Refer to the
for detailed operation modes.
1. The solar input is started (VOUT1 = Battery).
2. The VOUT1 voltage changes to solar energy when the VSTORE1 achieves VOUTH (3.24 V).
3. The VSTORE1 decreases when the solar input is stopped (VOUT1 = Solar).
4. The VOUT1 voltage changes to battery when the VSTORE1 achieves VOUTL (1.62 V).
5. The VSTORE1 increases when the solar input is restarted (VOUT1 = Battery).
6. The VOUT1 voltage changes to solar energy when the VSTORE1 re-achieves VOUTH (3.24 V).
