Hello,
I have a question regarding the buzzer output of the CY8CMBR3108. The datasheet at https://www.cypress.com/file/46236/download does not specify whether the buzzer output is push-pull or open drain. Figure 8 in the datasheet appears to suggest that the output signal is open drain. However, when I measure the voltage on the buzzer pin without anything connected to it, it is high.
Please note that I configured the CY8CMBR3108 to have a buzzer output signal on that pin.
Any help would be appreciated.
Thank you

Hi @Abdoulah
The BUZZER pin is driven by a PWM signal and therefore, the drive mode would be strong drive. The buzzer will be pulled high till there is some signal on the CapSense line.
Best regards,
Hari
