APPLICATION NOTE 4572
Reverse Battery Charger Protection
By:Zeeshawn Shameem, Customer Applications Engineer


Abstract:Combining a linear-mode single-cell lithium-ion battery charger (MAX1551) with a comparator (MAX9001) and n-
channel FET adds a layer of reverse-battery protection that protects a single cell lithium-ion battery charger and battery from
damage due to backwards insertion.
