More Information
Summary:The utility model discloses a load-open-circuit detection circuit, comprising a high side driver circuit module, a detection starting on-off circuit module connected with the high side driver circuit module, and a load-open-circuit detection circuit module connected with the detection starting on-off circuit module and used for load open circuit detection. According to the load-open-circuit detection circuit, leakage current for load open circuit detection is very low, a detection threshold can be adjusted according to load conditions, and when not in detection, the open circuit detection circuit is switched off, and no current is introduced.
