Our Advanced Drive Assist Systems(ADAS) project is based on Renesas RH850/U2A16 microcontroller. We are using Infineon Technologies TLE75620-EST, SPI Driver for Enhanced Relay Control IC for driving loads. Datasheet is attached. We don't have any loads connected to SPIDER output pins. We're not commanding digital output logic low or logic high. On power up, SPIDER digital outputs pins are not stable. They are toggling between logic high and logic low. Attached is SPIDER OUT0_HS pin...
Why isn't high side digital output stable?
