The customer got an enquiry about UCD90160ARGCR GPI response time.
In this particular project, they are using pin 32 “GPI2” as input pin to monitor thermal-Trip-L from the MCU.
Below is the waveform they captured during MCU thermal shutdown, Thermal-trip-L from MCU was low but only for 240us. But we noticed that UCD did not shut down the power rails. Is this 240us Low sufficient to be recognize by UCD as a fault event? Thank you.
Thermal-Trip# which is also Thermal-Trip-L has Fault Shutdown rails enabled.
