Abstract

An integrated circuit has a first pin, a voltage outputting circuit electrically connected to the first pin, a second pin, a current receiving circuit electrically connected to the second pin and a comparing circuit electrically connected to the current receiving circuit. The voltage outputting circuit outputs a first current which flow into the current receiving circuit through the second pin. After receiving the first current, the current receiving circuit outputs an output current to the comparing circuit and the comparing circuit compares the output current and a reference current to output an output signal.

Description

technical field [0001] The present invention relates to an integrated circuit, especially an integrated circuit that can provide information for users to judge the connection status of pins. Background technique [0002] In the prior art, in the process of assembling the liquid crystal display, it is often necessary to detect the connection status of the pins of the integrated circuit and the connection pads. The value method is more difficult and complicated, so how to effectively judge the pin connection status of the integrated circuit has become an issue to be solved. Contents of the invention [0003] An embodiment of the present invention discloses an integrated circuit. The integrated circuit includes a first pin, a first selection circuit electrically connected to the first pin, and a voltage output circuit electrically connected to the first selection circuit and outputs a first The current, the second pin, and the second selection circuit are used to electricall...
