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.
