Sensor And Detector Interfaces FAQ

How does the device handle power during signaling?

Power is passed through rectifiers to a holding capacitor (H_CAP), which stores energy during idle periods and supplies current during non-idle signaling periods.

What is the maximum voltage rating for the BUSIN and BUSOUT pins?

The maximum voltage rating for the BUSIN, BUSOUT, BUSRTN, and H_CAP pins is 40 V.

Can the I/O pins be configured dynamically?

Yes, the four I/O pins can be individually configured as logic inputs, logic outputs, or analog-to-digital inputs by the central MCU over the DSI bus.
