The TP4083 is a single-cell lithium battery charger with OVP (over-voltage protection), battery reverse polarity protection, and input power reverse polarity protection, all in a single chip. It supports a wide charging current range from 3mA to 500mA. Using trickle, constant current, and constant voltage control, the SOT23-6 or DFN2*2-6 package and minimal external components make the TP4083 an ideal choice for portable applications. The TP4083 is suitable for both USB power and adapter power sources.

+The SY6280 develops ultra-low Rds(on) switch with programmable current limiting to protect the power source from over current and short circuit conditions. It integrates the over temperature protection and discharges the output capacitor during the shutdown. In case the output is pulled higher than the input voltage under the shutdown, the SY6280 can block the current flowing from the output to the input.
