  • Publication number: 20250130673
    Abstract: An automotive touch circuit device includes: an analog front-end circuit, a first storage, a second storage, a micro control unit and an ESD protector. The analog front-end circuit has an ESD detector for detection to output a detection result signal. The first storage stores a control parameter having a first error detection code based on which a first error detection signal is generated. The second storage stores touch data having a second error detection code based on which a second error detection signal is generated. The micro control unit generates a notification signal based on the control parameter and touch data. When detecting no ESD interference, the ESD protector enables the notification signal to be output. When detecting ESD interference and an error detection result represented by one of the first and second error detection signals indicates an error, the ESD protector disables the notification signal to be output.
