The Mc34675 is a high-input-voltage Li-Ion battery charger with a 4.85V/10mA linear regulator. The high input voltage, up to 28V, eliminates the input over-voltage protection circuit required in handheld devices such as cell phones, Bluetooth accessories, and portable media players. The 4.85V linear regulator is capable of 10mA output current and can be used to directly power a sub-system such as a USB transceiver.
