Abstract

Cable failure protection and battery kickstart in an electronic device is provided. When the electronic device is attached to an external power supply via a universal serial bus type-C (USB-C) cable, it is important to protect the electronic device from being damaged by a cable failure (e.g., overcurrent, overtemperature, and/or faulty cable). Additionally, when a battery in the electronic device is fully depleted, it is necessary to kickstart recharging of the depleted battery upon attaching to the USB-C cable. Herein, a power management integrated circuit (PMIC) is provided in the electronic device and configured in accordance with the USB-C standard to protect the electronic device from the cable failure and kickstart recharging of the depleted battery. By integrating cable failure protection and battery kickstart functionalities into the PMIC, it is possible to reduce cost and footprint of the PMIC, thus making the PMIC suitable for small formfactor electronic devices.
