Abstract
Disclosed is an ink cartridge, ink cartridge chip, and short-circuit detection method of chip. The ink cartridge chip comprises: a short-circuit detection terminal, which is disposed between a connecting terminal to be detected and one or more connecting terminals other than the connecting terminal to be detected; a short-circuit detection and processing unit, which is connected to a voltage division and power supply unit and one or more connecting terminals other than the connecting terminal to be detected; and a voltage division and power supply unit, which is connected to the short-circuit detection and processing unit and the connecting terminal to be detected, for dividing voltage from the connecting terminal to be detected and transmitting an obtained low voltage to the short-circuit detection and processing unit. The present disclosure is able to reduce costs and satisfy long-term use of short-circuit detection in the ink cartridge chips.
