【Daily Highlight】SL3105A Linear Li-lon Battery Charger

The SL3105 Series is a complete constant current constant voltage linear charger for single cell lithium-ion batteries.Its DFN package and low external component counts make the SL3105 Seres ideally suited for portable applications.Furthemmore,the SL3105 Series is specifically designed to work within USB power specifications. No extemal sense resistor is needed,and no blocking diode is required due to the internal MOSFET architecture.The charge voltage is fixed at 4.2V/4.3V/4.35V/4.4V,and the charge current can be programmed externally with a single resistor.The SL3105 Series automatically terminates the charge cycle when the charge current drops to 1/10 the programmed value after the final float voltage is reached. When the input supply (wall adapter or USB supply)is removed.the SL3105 Series automatically enters a low current state,dropping the battery drain current to less than 2uA.The SL3105 Series can be put into shutdown mode, reducing the supply cumrent to 50uA. Under-voltage lockout,automatic recharge and two status pins to indicate charge and charge termination.

【Daily Highlight】SL4054 Linear Li-Ion Charger

The Slkor?4054 is a complete constant-current/constant-voltage linear charger for single cell lithium-ion batteries. Its SOP package and low external component count make the SL4054 ideally suited for portable applications. Furthermore, the SL4054 can work within USB and wall adapter. No blocking diode is required due to the internal PMOSFET architecture and have prevent to negative Charge Current Circuit. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The SL4054 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached. When removing input power automatically puts the SL4054 into a low current mode to reduce the battery's leakage current to below 2uA, and the shutdown mode reduces supply current to 45μA. SL4054 Other features include current monitor, under voltage lockout, automatic recharge and two status pin to indicate charge termination and the presence of an input voltage. The Slkor? SL4054 is available in a SOT23-5 (ThinSOTTM) package.
