MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202647081715 A) filed by Qualcomm Incorporated on July 02, 2026, for Techniques For Performing Soft Start For One Or More Batteries.
Inventors include Ding, Xinying; Guo, Guoyong; Yao, Qian; and Horovitz, Neal Number.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: Certain aspects of the present disclosure are directed towards techniques and apparatus for battery soft start. An example method generally includes: detecting connection of a first battery, wherein a first transistor is coupled between the first battery and an output node of a power supply circuit for the electronic device, and wherein an output capacitive element coupled to the output node; biasing the first transistor in a soft start operating mode to charge the output capacitive element based on the detection; detecting connection of a second battery, wherein a second transistor is coupled between the second battery and the output node; comparing a first battery voltage (VBAT) of the first battery and a second VBAT of the second battery; and biasing the first transistor in a second operating mode based on the comparison and an output voltage at the output node.
