1)Looking for low cost charger from 5V (not USB) for single cell LI-ION battery.
would like to have a control on other power supply rail
2)
For charging Lead-Acid, with 48V, with 4A charging, is the BQ24450 is the only solution we have?
Dose it has the option, to switch the system to the battery, when no Vin?
Can you recommend for simple solution that can give Empty/full battery status for protection?
