Having difficulty with a design meant to charge a typical 3.6v Lipo (650mAh) single cell from a solar panel that has been clamped down to 5.1V, (oc=7.8v) On all tries of the circuit we have VBAT_OV=4.1v First try of the circuit we had VBAT_OK set to 3.5V and VBAT_OK_HYST set to 4.0V. The battery never got past a charge of 3.4V Second try we had VBAT_OK set to 2.5V and VBAT_OK_HST set to 3.5V. This time, the battery could not charge past 3.2V. Any ideas?↧
