SGM41566 Linear Regulation Battery Charger
2023-12-18
■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 °C to +125 °C 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
