Application Notes

  • Current Limit Foldback Improves Short Circuit Protection in LM274X Family (Rev. B)
    PDF, 89 Kb, Revision: B, File published: Apr 23, 2013
    This application report discusses the function of the low side current limit used in the LM274X, andpresents a simple method to enhance the short-circuit protection. the current limit is required to protect thepower components from thermal stress, which can reduce life span. Typically, high side current limitdesigns require an internal rising edge blanking time or external filter to avoid no
