SGM40560 Small Capacity Compact Battery Charger for Loosely Coupled Wireless Charging/Solar Charging GENERAL DESCRIPTION FEATURES The SGM40560 is designed for the monolithic circuit with high-precision linear constant-current, and constant-voltage charging, which is specifically for small capacity Li-Ion/polymer Li-Ion secondary battery. It can complete the whole processes of pre-charge, fast-charge, trickle floating charge, voltage fold-back holding, resistive voltage drop compensation and recharge stand-alone. The maximum charge voltage is fixed with five options: ● Stand-Alone Working of Complete Processes for Single-Cell Battery Charging ● Suitable for Li-Ion Phosphate Battery/ Li-Ion/Polymer Li-Ion/Lithium Titanate/ Nickel-Metal Hydride Secondary Battery and EDLC Capacitor Charging ● Optional Maximum Charge Voltage: 3.65V to 5.5V ● High Accuracy Safe and Fast Charging ● 4% Output Voltage Fold-Back Holding Function ● Works with Loose Coupling Coil ● Works with Solar Batteries ● Saturated Conduction Charging ● Automatic Thermal Current Limit ● Power Saving Indication Mode ● Available in Green TDFN-2×2-6AL and SOIC-8 (Exposed Pad) Packages SGM40560-3.65 corresponds to 3.65V/3.709V/4.547V SGM40560-4.05 corresponds to 4.05V/4.108V/5.045V SGM40560-4.2 corresponds to 4.2V/4.257V/5.235V SGM40560-4.3 corresponds to 4.3V/4.356V/5.363V SGM40560-4.4 corresponds to 4.4V/4.466V/5.484V The charge current is set with the external resistor. The slow blinking LED indicates charging in progress and the continuous shining LED within a certain time indicates charging completion, which can be charged even with weak energy. It can operate with constant-voltage power supply, additionally, depending on its features and control structure. It can charge for the loose coupling coil with large voltage fluctuations and it also works for the solar batteries with reverse current. Therefore, it can provide flexible power supply options for wearable devices and mini portable devices. It has the voltage fold-back holding function and thermal current limit function so that the external power source can be used to supply power to the load for a long time safely and stably. APPLICATIONS Bluetooth Headsets, Bluetooth Mouses Wireless Thermometers, Wireless Oximeters, Wireless Pulsimeters Active Keys, Active Beacons Photovoltaic Storage Maintenance, Hub Dynamo Storage Maintenance The SGM40560 is available in Green TDFN-2×2-6AL and SOIC-8 (Exposed Pad) packages and is rated over the -40℃ to +125℃ temperature range.
