Publication number: 20230240006Abstract: An electronic device includes a circuit board having a signal detection terminal disposed on a first surface thereof and a ground terminal disposed on a second surface thereof and extending vertically so that the first surface and the second surface face each other in a horizontal direction, a monitoring terminal connected with the signal detection terminal, and a microcontroller unit (MCU) determining whether there is submersion by monitoring a voltage at the monitoring terminal. According to the present embodiments, it is possible to prevent hypersensitivity-induced misdetection due to condensation and dew. It is also possible to stepwise respond to submersion and determine whether the monitoring circuit normally operates to precisely detect submersion.Type: ApplicationFiled: January 20, 2023Publication date: July 27, 2023Applicant: HL MANDO CORPORATIONInventors: Su Min LEE, Kyu Yeong JE

Patent number: 11223195Abstract: A control device and method for power supply to an EPS system in a vehicle, including a reverse voltage protection circuit and a battery disconnect circuit. A DC-end capacitor is charged with a voltage by turning on switches of a reverse voltage protection circuit and a battery disconnect circuit, a change in the voltage of the DC-end capacitor is detected by turning off the switches of the reverse voltage protection circuit and the battery disconnect circuit, and then a failure in the switches of the reverse voltage protection circuit and the battery disconnect circuit is determined on the basis of information regarding changes in the voltage of the DC-end capacitor. The failure in the reverse voltage protection circuit and the battery disconnect circuit is diagnosed without a charge/discharge circuit.Type: GrantFiled: June 19, 2019Date of Patent: January 11, 2022Assignee: MANDO CORPORATIONInventors: Jong Mu Lee, Su-Min Lee, Kyu Yeong Je
