Title:
IGNITION WAKE-UP CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2024/039101
Kind Code:
A1
Abstract:
An ignition wake-up circuit, according to an embodiment of the present invention, comprises: an input node receiving an ignition voltage as an input; an output node outputting a wake-up voltage; and a voltage sensing unit outputting a wake-up signal according to the magnitude of the ignition voltage. The voltage sensing unit outputs the wake-up signal when the ignition voltage reaches a voltage level greater than or equal to a first reference voltage from a voltage less than the first reference voltage, and outputs a low signal when the ignition voltage reaches a voltage level less than or equal to a second reference voltage from a voltage greater than the second reference voltage, and the first reference voltage is greater than the second reference voltage.
