SGM40567
Small Capacity Compact Battery Charger for Loosely Coupled Wireless Charging/Solar Charging
The SGM40567 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:
SGM40567-3.65 corresponds to 3.65V/3.709V/4.547V
SGM40567-4.05 corresponds to 4.05V/4.108V/5.047V
SGM40567-4.2 corresponds to 4.2V/4.257V/5.237V
SGM40567-4.3 corresponds to 4.3V/4.356V/5.367V
SGM40567-4.4 corresponds to 4.4V/4.466V/5.489V
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.
The SGM40567 is available in a Green WLCSP-0.92×1.16-6B package and is rated over the -40℃ to +125℃ temperature range.
