Super-low-poweroperation is possible using a consumption current of only 250 nA and startup power of only 1.2 μW. As a result, even slight amountsof power generation can be obtained from compact solar cells under low-brightness environments of approximately 100 lx. TheS6AE101A stores power generated by solar cells to an output capacitor using built-in switch control, and it turns on the powerswitching circuit while the capacitor voltage is within a preset maximum and minimum range for supplying energy to a load. If thepower generated from solar cells is not enough, energy can also be supplied in the same way as solar cells from connected primarybatteries for auxiliary power. Also, an over voltage protection (OVP) function is built into the input pins of the solar cells, and theopen voltage of solar cells is used by this IC to prevent an overvoltage state. The S6AE101A is provided as a battery-free wirelesssensor node solution that is operable by super-compact solar cells.S6SAE101A主要特性:Input power selection control: Solar cell or primary batteryOperated by solar cells without the need for primary batteriesStorage of energy from power supply to storage capacitorsOutput power gating control, output voltage regulationOperation input voltage rangeSolar cell power : 2.0V to 5.5VPrimary battery power : 2.0V to 5.5VAdjustable output voltage range : 1.1V to 5.
