S6AE101A数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The S6AE101A is a power management IC (PMIC) for energy harvesting that is built into circuits of series solar cell connection, output voltage control circuits, output capacitor storage circuits, and power select 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.\r
\r
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.\r
\r
Also, an overvoltage 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.\r
\r
The S6AE101A is provided as a battery-free wireless sensor node solution that is operable by super-compact solar cells.
