Abstract
Systems, circuits, and devices for reducing leakage current in a mobile device with an embedded battery are disclosed. In one embodiment, a system for reducing leakage current in a mobile device with an embedded battery comprises a power management integrated circuit (PMIC), a switch device electrically coupled to the embedded battery and the PMIC, and a low power personal area network (PAN) module coupled to the embedded battery, the PMIC, and the switch device. The low power PAN module is configured to maintain the switch device in an open state while an application processor (AP) of the mobile device is off and to close the switch device in response to a receipt of an AP ON request signal to wake up the AP, where the open state of the switch device blocks leakage current flowing from the battery to the PMIC.
