The CXLB7295 is a complete single cell Li-ion battery powered by constant current/constant voltage linear charger. The SOP8/MSOP package with a heat sink at the bottom and a small number of external components make the CXLB7295 ideal for portable applications. CXLB7295 can work with USB power supply and adapter power supply.
Due to the internal PMOSFET architecture, plus the anti-back circuit, there is no need for external isolation diodes. Thermal feedback automatically adjusts the charging current to limit the chip temperature during high power operation or high ambient temperature conditions. The charging voltage is fixed at 4.2V, while the charging current can be set externally via a resistor. When the charging current drops to 1/10 of the set value after reaching the final float voltage, the CXLB7295 will automatically terminate the charging cycle.
When the input voltage (AC adapter or USB power) is removed, the CXLB7295 automatically enters a low current state, reducing the battery drain current to less than 2uA. CXLB7295 when there is a power supply, it can also be placed in shutdown mode to reduce the supply current to 55uA. Other features of the CXLB7295 include battery temperature detection, undervoltage lockout, automatic recharge, and two LED status pins to indicate charging and completion.
