MULTI-PURPOSE POWER MANAGEMENT CHIP AND POWER PATH CONTROL CIRCUIT

The present invention discloses a multi-purpose power management chip and a power path control circuit. The multi-purpose power management chip includes: a switch circuit including at least one power transistor; a switch control circuit for generating a first switch signal to control an operation of the power transistor to thereby control the power conversion between an input terminal and an output terminal; a power path management circuit for controlling the charging operation from the output terminal to the battery; a current source for supplying a current to the battery; and a path selection circuit for determining whether the charging operation to the battery is controlled by the power path management circuit and the current source or not according to whether a power path power transistor is provided on the power path or not.
