Abstract
A temperature control circuit of a driver chip, a temperature control method of the driver chip, a power management integrated chip, a timing control driver board and a display apparatus are disclosed. The temperature control circuit includes a switching transistor, a comparison circuit and a control circuit; a first electrode of the switching transistor is connected with a first node, a second comparison end and the first electrode or a second electrode of the switching transistor are connected to a second node; the control circuit is configured to output a first reference voltage to the comparison circuit, the comparison circuit is configured to compare a magnitude relationship between a voltage on the second comparison end and the first reference voltage and output a comparison result; the control circuit acquires the comparison result and determines whether an output current on the boost circuit is excessively large.
