Typical application circuit

Optional resistors REN and RFLT prevent damage to the controller under extreme voltage or current conditions and are not

required. Low ESR ceramic capacitor C1 is necessary to ensure proper function of the STBP110. Capacitor C2 is not

necessary for STBP110 but may be required by the charger IC.

The STBP110 MOSFET switch topology allows the current to flow also in a reverse direction, i.e. from OUT to IN, which

can be useful for powering external peripherals from the system connector. If the reverse current (supply current) is

undesirable, it may be prevented by connecting an external Schottky diode in series with the OUT pin. The voltage drop

between IN and the charger is then increased by the voltage drop across the diode.
