GENERAL DESCRIPTION

The SGM41566 is designed for charging low capacity

battery cell with factory-programmable current

programmable in the range of 50mA to 750mA from

loosen regulated power source. The device features

low drop-out constant-current constant-voltage

charging, weak battery pre-charging, voltage fold-back

safe retaining, floating charging protection and system

start-up pre-charge, with NTC sensing protection.

The SGM41566 is available in a Green TDFN-2×2-8AL

package. It operates in -40℃ to +125℃ junction

temperature.
