S6AE101A
Energy Harvesting PMIC
for Wireless Sensor Node
The S6AE101A is a power management IC (PMIC) for energy harvesting that is built into circuits of solar cells connected in series,
output power control circuits, output capacitor storage circuits, and power switching circuits of primary batteries. Super-low-power
operation is possible using a consumption current of only 250 nA and startup power of only 1.2 µW. As a result, even slight amounts
of power generation can be obtained from compact solar cells under low-brightness environments of approximately 100 lx. The
S6AE101A stores power generated by solar cells to an output capacitor using built-in switch control, and it turns on the power
switching circuit while the capacitor voltage is within a preset maximum and minimum range for supplying energy to a load. If the
power generated from solar cells is not enough, energy can also be supplied in the same way as solar cells from connected primary
batteries for auxiliary power. Also, an over voltage protection (OVP) function is built into the input pins of the solar cells, and the
open voltage of solar cells is used by this IC to prevent an overvoltage state. The S6AE101A is provided as a battery-free wireless
sensor node solution that is operable by super-compact solar cells.

7. Functional Description
7.1
Power Supply Control
This IC can operate by two input power supplies, namely, the solar cell voltage VDD and the primary battery voltage VBAT. The
voltages at the VDD pin and VBAT pin are monitored, and selection control of the input power supply is performed based on this
voltage state (Figure 7-1).
The input power (solar cell or primary battery) is temporarily stored to a capacitor connected to the VSTORE1 pin. When the voltage
of the VSTORE1 pin reaches a certain threshold value or higher, the power switching switch (SW1) connects VSTORE1 and
VOUT1.

1. VDD input voltage operation
This section describes operation when the VDD pin is set as the input power (Figure 7-2).
[1] When the voltage of the VDD pin reaches the power detection voltage (VDETH = 1.55V) or higher, the switch (SW2) connects
VDD and VSTORE1 (path S1). Also, when the voltage of the VDD pin falls to the power undetection voltage (VDETL = 1.45V)
or less, SW2 disconnects the path S1.
[2] When the voltage of the VSTORE1 pin reaches the threshold value (VVOUTH) or higher that was set by the SET_VOUTH pin,
SW2 disconnects the path S1. Also, the VOUT switch (SW1) connects VSTORE1 and VOUT1 (path S2).
[3] When the voltage of the VSTORE1 pin falls to the input power reconnect voltage (VVOUTM) or less, SW2 connects the path S1
(path S1+S2).
[4] In addition, when the voltage falls to the threshold value (VVOUTL) or less that was set by the SET_VOUTL pin, SW1
disconnects the path S2.
[5] When SW1 disconnects the path S2, the discharge function is activated.

2. VBAT input voltage operation
This section describes operation when the VBAT pin is set as the input power (Figure 10-3).
[1] When the voltage of the VBAT pin reaches the power detection voltage (VDETH = 1.55V) or higher, the switch (SW2)
connects VBAT and VSTORE1 (path S3). Also, when the voltage of the VDD pin falls to the power undetection voltage
(VDETL = 1.45V) or less, SW4 disconnects the path S3.
[2] When the voltage of the VSTORE1 pin reaches the threshold value (VVOUTH) or higher that was set by the SET_VOUTH pin,
SW4 disconnects the path S3. Also, the VOUT switch (SW1) connects VSTORE1 and VOUT1 (path S2).
[3] When the voltage of the VSTORE1 pin falls to the input power reconnect voltage (VVOUTM) or less, SW4 connects the path
S3 (path S3+S2).
[4] In addition, when the voltage falls to the threshold value (VVOUTL) or less that was set by the SET_VOUTL pin, SW1
disconnects the path S2.
[5] When SW1 disconnects the path S2, the discharge function is activated.

3. Input power supply switching
This section describes the input power switching operation (Figure 7-4).
[1] If the voltages of the VDD pin and VBAT pin increase from a state where both are less than the power detection voltage
(VDETH = 1.55V) so that the voltage of the VDD pin reaches the power detection voltage (VDETH = 1.55V) or higher, and
operation switches to VDD input power operation back from the stage of disconnecting all paths.
[2] When the voltage of the VBAT pin increases to the power detection voltage (VDETH = 1.55V) or higher, if the power from the
solar cell is reduced, and when the voltage of the VDD pin falls to the power undetection voltage (VDETL = 1.45V) or less,
operation switches from VDD input power operation to VBAT input power operation.
[3] When the amount of power supplied from the solar cell increases, and the voltage of the VDD pin reaches the power
detection voltage (VDETH = 1.55V) or higher, operation switches back to VDD input power operation. After switching, operation
is performed based on VDD input power operation.

Power Gating
This IC has a power gating function for the external system. Once it is detected that the voltage of the VSTORE1 pin has reached
the VOUT maximum voltage (VVOUTH), the VSTORE1 pin and VOUT pin are connected by an internal switch until the VOUT
minimum voltage (VVOUTL) is reached.

Discharge
This IC includes a VOUT1 pin discharge function.
When SW1 disconnects the VSTORE1 and VOUT1 path, the discharge circuit is activated between the VOUT1 pin and GND. The
power of the VOUT1 pin is discharged to the GND level.
7.4
Over Voltage Protection (OVP Block)
This IC includes an input overvoltage protection (OVP) function for the VDD pin voltage.
When the VDD pin voltage reaches the OVP detection voltage (VOVPH=5.4V) or higher, the OVP current (IOVP) from the VDD pin is
drawn in for limiting the increase in the VDD pin voltage for preventing damage to the IC. Also, when the OVP release voltage
(VOVPL=5.3V) or less is reached, drawing-in of the OVP current is stopped.

Setting the Operation Conditions
Setting of output voltage (VOUT1)
The resistor connecting the SET_VOUTH pin and SET_VOUTL pin can be changed to set the VOUT1 output voltage of this IC. This
is because the VOUT maximum voltage (VVOUTH) and VOUT minimum voltage (VVOUTL) are set based on the connected resistance.
The SET_VOUTFB pin outputs a reference voltage for setting the VOUT maximum voltage and VOUT minimum voltage. Resistor
voltage division can be performed on this reference voltage outside the IC for creating a voltage applied to the SET_VOUTH pin and
SET_VOUTL pin.

PCB Layout
Take into account the following points when designing the layout.
 Try
to route the wiring for the diode (D1) and input capacitor (C1) for connecting the solar cell on the top layer as m
uch as possible, and avoid implementing a connection using a through hole.
 For the AGND pin of S6AE101A, provide a through hole nearby, and connect it to the GND plane.
 Locate the capacitor (C2) for the internal power as near as possible to the VINT pin.
 Locate the resistors (R1, R2, R3) for setting the output voltage in a grid-type configuration with small loops, and locat
e them as near as possible to each pin (SET_VOUTFB, SET_VOUTH, SET_VOUTL). Also, removing the GND plane
under the parts can be effective in preventing malfunctions due to the leakage current.
 To prevent a leakage current, locate and route the storage capacitor (C3) as far as possible from patterns that are dif
ferent from the electrical potential of VSTORE1 (such as the GND line). Generally, the insulation resistor of printed cir
cuit boards is extremely high, and normally, the passing of leakage current through the board does not pose a proble
m. However, in certain rare cases, the surface of the board may have a low insulation resistance, and when using th
ese boards, a leakage current that cannot be ignored may occur.

12. Usage Precaution
Printed circuit board ground lines should be set up with consideration for common impedance.
Take appropriate measures against static electricity.
 Containers
for semiconductor materials should have anti−static protection or be made of conductive material.
mounting, printed circuit boards should be stored and shipped in conductive bags or containers.
 Work platforms, tools, and instruments should be properly grounded.
 Working personnel should be grounded with resistance of 250 kΩ to 1 MΩ in serial body and ground.
 After
Do not apply negative voltages.
The use of negative voltages below −0.3 V may make the parasitic transistor activated to the LSI, and can cause malfunctions.
