An output circuit which may be used in a battery pack, such as those used to provide a charge to a portable electronic device. The output circuit includes an output MOSFET having a gate and forming an open drain circuit, and a CMOS drive transistor. The CMOS drive transistor has a PMOS transistor, an NMOS transistor, an input terminal and an output terminal. The input terminal receives a drive control signal and the output terminal is connected to the gate of the output MOSFET. When the drive control signal is active, the PMOS transistor is turned off and the output MOSFET is turned on, such that power is provided at the output terminal of the output circuit via the output MOSFET. The output circuit provides improved power consumption characteristics so that the battery charge is not unnecessarily drained.
