SGM41566 Linear Regulation Battery Charger
2023-01-05
●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.
●FEATURES
■Loosen Regulated Power Input
■Battery Voltages Option: 25mV Raster in 3.5V to 4.8V Range
■Charging Current Option: 50mA Raster in 50mA to 750mA Range
■5% to 25% Residual End-of-Charge Option
■Weak Battery Pre-Charge Option
■Voltage Fold-Back Safe Power Retaining
■NTC Temperature Sensing for Protection
■Floating Charging Protection
■Start-Up Charging for 12.5ms
■650ms Power Recycle Certification
■Full Charging Power-Up at Low Voltage
■Pre-Charging Power-Up at Normal Voltage
■Available in a Green TDFN-2×2-8AL Package
