  • Small highly accurate battery temperature monitoring circuit
    Patent number: 9863817
    Abstract: A battery temperature monitoring circuit, which has a cold comparator and a hot comparator, achieves high accuracy in a small cell size by utilizing a cold current optimized for the cold comparator and a cold reference voltage, and a hot current optimized for the hot comparator and a hot reference voltage, along with switching circuitry that provides the cold current to the cold comparator as the battery temperature approaches the cold trip temperature, and the hot current to the hot comparator as the battery temperature approaches the hot trip temperature.
    Type: Grant
    Filed: October 21, 2014
    Date of Patent: January 9, 2018
    Assignee: NATIONAL SEMICONDUCTOR CORPORATION
    Inventors: Luan Minh Vu, Thomas Y. Tse, Tuong Hoang
