Abstract

Intelligent power integrated circuit chips play an increasingly important role in industrial automation, domestic medical appliances, automotive electronics, especially in modern military, aerospace and other fields. Based on the analysis of the current front-end verification problem of digital application specific integrated chip, the composition and working principle of motor drive chip, the design and composition technology of undervoltage protection function module and the perfect protection circuit not only ensure that the chip can work normally under some harsh conditions, but also play a vital role in the safety of the whole system sometimes. After the motor chip is verified by the flow sheet, packaging, testing and test result analysis are carried out to further predict and adjust the function and reliability of the motor chip. On the basis of analyzing the current front-end verification problem of digital application specific integrated chip, the circuit structure is simple, no additional bandgap reference circuit is needed, and the voltage comparator circuit is also omitted.
