The power stage includes a metal-oxide semiconductor field-effect transistor (MOSFET) and a driver IC coupled to the MOSFET. The driver IC is configured to switch the MOSFET to an ON-state so that MOSFET conducts a current. The driver IC includes a current monitor circuit that outputs a current monitor signal, which corresponds to the current through the MOSFET when it is in the ON-state. The current monitor signal includes an error caused by a temperature difference between the MOSFET and the driver IC. As a result, the driver IC further includes a compensation circuit that is configured to determine a thermal gradient across the driver IC, and based on the thermal gradient, adjust the current monitor circuit to reduce the error.Type: ApplicationFiled: October 3, 2018Publication date: April 9, 2020Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Zhiwei LIU, Marc DAGAN, Kaiwei YAO

Publication number: 20200110130Abstract: A self-check system and a method thereof are disclosed. In the self-check system, a memory stores a safety check program, a main application program and a predetermined checksum data. The safety check program include a circuit check program, a watchdog circuit reset program and a checksum check program. When a chip system is powered on, a processing unit executes the main application program, and then executes an interrupt call to generate an interrupt, so as to execute the safety check program and the circuit check program to check a to-be-checked circuit. The processing unit also executes the watchdog circuit reset program to reset a counting value of a watchdog circuit. The processing unit also executes the checksum check program to calculate a checksum data of the first safety check program, and reset the chip system when the calculated checksum data is not equal to the predetermined checksum data.Type: ApplicationFiled: April 4, 2019Publication date: April 9, 2020Inventors: CHIH-KAI HUANG, PING-YING CHU, CHIH-SHIEN YANG

Publication number: 20200110132Abstract: A synchronization circuit includes a first synchronizer, a second synchronizer, and selection circuitry. The first synchronizer is configured to synchronize a received signal to a clock signal. The second synchronizer is disposed in parallel with the first synchronizer and configured to synchronize the received signal to the clock signal. The selection circuitry is coupled to the first synchronizer and the second synchronizer. The selection circuitry is configured to provide an output value generated by the first synchronizer at an output terminal of the synchronization circuit based on the output value generated by the first synchronizer being the same as an output value generated by the second synchronizer.Type: ApplicationFiled: October 5, 2018Publication date: April 9, 2020Inventors: Denis Roland BEAUDOIN, Samuel Paul VISALLI

Publication number: 20200110133Abstract: A rotor bar fault in a rotor of an electrical machine having a plurality of rotor bars and an end ring configured to short circuit the rotor bars. The method includes the steps of measuring a first temperature at a first end ring location, and measuring a second temperature at a second end ring location, the second end ring location being different from the first end ring location. As broken rotor bars cause a non-uniform temperature distribution in the end ring, the detection of rotor bar faults can be based on monitored temperatures at different end ring locations.Type: ApplicationFiled: March 6, 2018Publication date: April 9, 2020Inventors: Pedro Rodriguez, Subrat Sahoo

Publication number: 20200110134Abstract: In a status detection system, a data acquisition circuit monitors statuses of a battery to generate status data. A storage medium stores a set of lookup tables. A lookup table of the lookup tables includes a set of datasets corresponding to a set of time frames. Each dataset includes digital values of parameters of the battery obtained in a corresponding time frame of the time frames. A controller receives the status data and updates the lookup tables based on the status data. The controller also obtains a current dataset of the parameters based on the status data, searches the lookup table for a previous dataset that matches the current dataset, compares a current value of a parameter in the current dataset with a previous value of the parameter in the previous dataset, and determines whether a potential fault is present in the battery based on a result of the comparison.Type: ApplicationFiled: July 16, 2019Publication date: April 9, 2020Inventor: Guoxing LI
