... Note 4: For logic-high, connect LCE to the REG output. Do not connect to the BATT or PCKP pins. Note 5: Since LCE is compared to the REG pin voltage for operation, the low-power regulator cannot be switched off under condi- tions where the REG output is shorted to GND.

... High voltage and low 0.22 voltage > 10FW Maxim Integrated CHG Capacitor This is the minimum size required for operation. Increasing the size of the harvest source capacitor beyond this level improves charge circuit efficiency at extremely low input power (< 10FW), but care should be taken not to increase the capacitor so large that the harvest source cannot overcome the capacitor’ ...

... The LDO supports loads up to 75mA (high-current mode). For lighter load applications, a low-power mode of operation reduces the quiescent current drain on the cell. A UVLO circuit prevents the regulator from start- ing up or disabling the regulator when active if the cell becomes overdischarged. Maxim Integrated - ( OFF - 0 ...

... Maxim Integrated addition to voltage protection, the ramp of the PCKP switch impedance is changed slowly (5ms to full on) to gradually load the cell and not collapse the voltage on a room-temperature cell. Because of these protection fea- tures, an application can now support brief high-current pulses by including a large capacitance at PCKP ...
