I am designing a solar powered device from a 22V (maximum) solar panel and a 3.7V 4000mAh (1S2P) battery, but the datasheet says nothing about the battery undervoltage lockout.
Does the LTC4091 have battery overdischarge protection? If…
I designed a circuit based on DC2558A development board, the problem is when battery voltage is higher than 3.6V, the LTC4091 seems not provide charging current.
Thanks for any help.
we designed a circuit based on LTC4091. The circuit is an almost identical clone of the DC2558A development board (that we do not have, by the way). The only difference is that the output current is set a little higher as well as frequency.
Kindly suggest me a part similar to LTC4091 which can act as backup switch and charging LI-Ion 7.4v Battery
