 (G5242 SOT23-5 package, the maximum charge current set to work long hours up to 500MA) 

 G5242 is the constant current / constant voltage linear charger chip, mainly for single Li-ion battery charging applications. G5242 small SOT23 package and with the least number of external components is ideal for portable equipment applications. G5242 can be powered via USB to the battery, but also can be used as stand-alone Li-ion battery charger. 







 G5242 without external sense resistor, MOSFET and because the internal structure, so no external reverse diode. Thermal feedback circuit to G5242 in the high-power and high ambient temperature can be adjusted to limit the charge current the chip temperature. G5242 of the charging voltage is fixed at 4.2V, charge current set by external resistors. When the float voltage and charge current reaches down to the set current 1 / 10, G5242 automatically terminates the charge process. 





 With thermal protection trickle charge current charge large precision charge voltage and other functions. 

 Circuit is very simple, only two resistors a capacitor to form an LED indicator light programmable charge current regulation of the professional circuit. 







 G5242 according to application requirements, constitutes a double LED light indication. Specific application circuit, please contact us
