Title:
POWER SOURCE CHIP TESTING CIRCUIT, POWER SOURCE CHIP TESTING METHOD AND APPARATUS, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/206646
Kind Code:
A1
Abstract:
A power source chip testing circuit (200), a power source chip testing method and apparatus (1000), and an electronic device (1100), which belong to the technical field of power source testing. The power source chip testing circuit (200) comprises a voltage isolation unit and a voltage conversion unit. The voltage isolation unit can acquire a switch voltage signal on a switch pin in a power source chip, and isolate a direct current component in the switch voltage signal, so as to obtain an alternating current component in the switch voltage signal. The voltage conversion unit can convert the alternating current component into a signal that can indicate whether the power source chip is faulty.
