S6AE102A / S6AE103A
Energy Harvesting PMIC
for Wireless Sensor Node
The S6AE102A/103A is a power management IC (PMIC) for energy harvesting that is built into circuits of solar cells connected in
series, dual output power control circuits, output capacitor storage circuits, power switching circuits of primary batteries, a LDO, a
comparator and timers. Super-low-power operation is possible using a consumption current of only 280 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. This IC 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. The output power control circuit has 2 outputs, and 1 of 2 outputs can control On and OFF of the power
gating circuit using interrupt signal. The output capacitor storage circuits have 2 capacitor connection circuit for a storage of system
load and a storage of surplus power, and if the power generated from solar cells is enough, the power is stored to the capacitor of
surplus power storage. If the power generated from solar cells is not enough, energy can also be supplied in the same way as solar
cells from the capacitor of surplus power storage or connected primary batteries for auxiliary power. This IC has also an
independent LDO. The LDO can provide stable voltage that a sensor requires. And also an independent comparator which can
make voltage comparison signal output a lot of flexibility is built in. 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 over voltage state. The
S6AE102A/103A is provided as a battery-free wireless sensor node solution that is operable by super-compact solar cells or
non-disconnect energy harvesting based wireless sensor node solution with the capacitor of surplus storage or primary batteries for
auxiliary power.

9. Functional Description
9.1
Power Supply Control
This IC can operate by two input power supplies, namely, the solar cell voltage VDD and the primary battery voltage VBAT.
When a capacitor is connected to the VSTORE2 pin, the surplus power of the solar cell accumulates in this capacitor and operates
as input power supply.
The input power (from solar cell) is accumulated once in the capacitor connected to the VSTORE1 pin. When the voltage of the
VSTORE1 pin reaches the threshold or higher, the power gating switch connects VSTORE1 to VOUT1 and VOUT2.
The input power (from primary battery) is not accumulated in the capacitor connected to the VSTORE1 pin. When the voltage of the
VBAT pin reaches the threshold or higher, the switch for power gating connects VBAT to VOUT1 and VOUT2.
The VINT pin voltage is output as shown in the table below.

VDD Input Power Operation
This section describes operation when the VDD pin is set as the input power (Figure 9-1).
When the voltage of the VBAT pin falls to the power undetection voltage (VDETL = 1.45 V) or less, and a capacitor is not connected to
the VSTORE2 pin.
[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 VOUT1 switch (SW1) connects VSTORE1 and VOUT1, and the VOUT2 switch
(SW6) connects VSTORE1 and VOUT2 (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 and SW6
disconnect the path S2.
[5] When SW1 and SW6 disconnects the path S2, the discharge function is activated.

Power Gating
This IC has a power gating function for external systems.
The power gating function is to control supplying power accumulated in VSTORE1 or power from VBAT to external system loads
connected to VOUT1 and VOUT2 by internal switches.
The power gating function has four operating modes.
This IC determines the power gating operation mode through the connection status of pins CIN1 and CIN2 at the power detection
(VDETH = 1.55 V) timing of the VINT pin.

Energy Driven Mode
1) VDD input power operation
Switches are controlled by monitoring VSTORE1 voltage.
Internal switches (SW1 and SW6) connect VSTORE1 and VOUT1, as well as VSTORE1 and VOUT2 from when VOUT upper
limit voltage (VVOUTH) is detected until VOUT lower limit (VVOUTL) is detected.
2) VBAT input power operation
Switches are controlled by monitoring VBAT voltage.
Internal switches (SW4 and SW10) connect VBAT and VOUT1, as well as VBAT and VOUT2 from when power detection voltage
(VDETH) is detected until power undetection voltage (VDETL) is detected.
Event Driven Mode 1
Switches are controlled in the same way as the energy driven mode to supply to VOUT1. The INT input controls switching to supply
to VOUT2. While the timer 0 is counting, the flag output (T0TM) disables internal switching controls through INT input. The timer
time (T0) is set by the capacitor connected to CIN0.
1) VDD input power operation
Internal switch (SW6) connects VSTORE1 to VOUT2 while INT is high level. Detecting upper limit voltage (V VOUTH) is a trigger to
start timer 0, after the timer time reaches count (T0), it stops and is reset.
2) VBAT input power operation
Internal switch (SW10) connects VBAT to VOUT2 while INT is high level. Detecting power detection voltage (V DETH) is a trigger to
start timer 0, after the timer time reaches count (T0), it stops and is reset.
Event Driven Mode 2
Switches are controlled in the same way as the energy driven mode to supply to VOUT1. The INT input and the flag output (T1TM)
control switching to supply to VOUT2.
1) VDD input power operation
Detecting upper limit voltage (VVOUTH) is a trigger to start counter, after the timer time reaches count (T0), timer 0 stops and is
reset. When the timer time (T0) is set by the capacitor connected to CIN0.
The highness of INT is a trigger to start counter, after the timer time reaches count (T1), timer 1 stops and is reset. When the
timer time (T1) is set by the capacitor connected to CIN1.
For each timer, they are reset by detecting VOUT lower limit voltage (V VOUTL).
Internal switch (SW6) connects VSTORE1 to VOUT2 while timer 1 is counting. Disables internal switching controls through INT
input while the timer 0 is counting.

S6AE102A / S6AE103A
2) VBAT input power operation
Detecting power detection voltage (VDETH) is a trigger to start counter, after the timer time reaches count (T0), timer 0 stops and is
reset. When the timer time (T0) is set by the capacitor connected to CIN0.
The highness of INT is a trigger to start counter, after the timer time reaches count (T1), timer 1 stops and is reset. When the
timer time (T1) is set by the capacitor connected to CIN1.
Each timer is reset by detecting power undetection voltage (V DETL).
Internal switch (SW10) connects VBAT to VOUT2 while timer 1 is counting. Disables internal switching controls through INT input
while the timer 0 is counting.
Timer Driven Mode
The timer 0 flag output (T0TM), timer 1 flag output (T1TM), and timer 2 flag output (T2TM) control switching to supply to VOUT1 and
VOUT2
1) VDD input power operation
This section describes the operation of each timer.
Detecting upper limit voltage (VVOUTH) the first time is a trigger to start counter, after the timer time reaches count (T0), timer 0
stops and is reset. From the second time onward, the completion of timer 2 is a trigger to start the count, after the timer time
reaches count (T0), the timer stops and is reset. When the timer time (T0) is set by the capacitor connected to CIN0.
Detecting upper limit voltage (VVOUTH) the first time is a trigger to start counter, after the timer time reaches count (T1), timer 1
stops and is reset. From the second time onward, the completion of timer 2 is a trigger to start the count, after the timer time
reaches count (T1), the timer stops and is reset. When the timer time (T1) is set by the capacitor connected to CIN1.
The completion of timer 1 is a trigger to start counter, after the timer time reaches count (T2), timer 2 stops and is reset. When
the timer time (T2) is set by the capacitor connected to CIN2.
Timer 0 and 1 are reset by detecting VOUT lower limit voltage (VVOUTL). Timer 2 is reset by power undetection voltage (V DETL)
of VINT.
This section describes the operation of VOUT1.
Internal switch (SW1) connects VSTORE1 to VOUT1 while timer 1 is counting. Internal switch (SW1) disconnects VSTORE1
and VOUT1 while timer 2 is counting.
This section describes the operation of VOUT2.
Internal switch (SW6) connects VSTORE1 to VOUT2 while timer 1 is counting after timer 0 ends. Internal switch (SW6)
disconnects VSTORE1 and VOUT2 while timer 2 is counting.
2) VBAT input power operation
This section describes the operation of each timer.
Detecting power detection voltage (VDETH) the first time is a trigger to start counter, after the timer time reaches count (T0),
timer 0 stops and is reset. From the second time onward, the completion of timer 2 is a trigger to start the count, after the timer
time reaches count (T0), the timer stops and is reset. When the timer time (T0) is set by the capacitor connected to CIN0.
Detecting power detection voltage (VDETH) the first time is a trigger to start counter, after the timer time reaches count (T1),
timer 1 stops and is reset. From the second time onward, the completion of timer 2 is a trigger to start the count, after the timer
time reaches count (T1), the timer stops and is reset. When the timer time (T1) is set by the capacitor connected to CIN1.
The completion of timer 1 is a trigger to start counter, after the timer time reaches count (T2), timer 2 stops and is reset. When
the timer time (T2) is set by the capacitor connected to CIN2.
Each timer is reset by detecting power undetection voltage (VDETL).
This section describes the operation of VOUT1.
Internal switch (SW4) connects VBAT to VOUT1 while timer 1 is counting. Internal switch (SW4) disconnects VBAT and
VOUT1 while timer 2 is counting.
This section describes the operation of VOUT2.

Over Voltage Protection (OVP)
This IC has an input over voltage 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.

11. Application Note
11.1 Setting the Operation Conditions
Setting of Output Voltage (VOUT1, VOUT2)
The VOUT1 and VOUT2 output voltage of this IC can be set by changing the resistors connecting the SET_VOUTH pin and
SET_VOUTL pin. This is because the VOUT upper limit voltage (VVOUTH) and VOUT lower limit voltage (VVOUTL) are set based on the
connected resistors. The SET_VOUTFB pin outputs a reference voltage for setting the VOUT upper limit voltage and VOUT lower
limit voltage. The voltages applied to the SET_VOUTH and SET_VOUTL pins are produced by dividing this reference voltage
outside the IC.
