The SGM40561 is a fully integrated high input voltage single-cell Li-ion battery charger. The charger uses a CC/CV charge profile required by Li-ion battery. The charger accepts an input voltage up to 26.5V but is disabled when the input voltage exceeds the OVP threshold, typically 10.5V, to prevent excessive power dissipation. The 26.5V rating eliminates the overvoltage protection circuit required in a low input voltage charger.
