Latest Patents

Wei-Chih Cheng holds a patent for a "Voltage detection device and voltage protection method." This innovative device includes a voltage divider circuit, a comparator circuit, and a switch control circuit. The voltage divider circuit operates in a first mode based on a switching signal, dividing a power voltage to generate an input voltage. The comparator circuit then compares this input voltage with a set of reference voltages to generate a detection signal. After a predetermined period from the power-on of the power voltage, the switch control circuit selectively adjusts the switching signal according to the detection signal, allowing the voltage divider circuit to switch from the first mode to a second mode. The first mode corresponds to a higher target level of the power voltage, while the second mode corresponds to a lower target level.
