Fault reported by Serial Output (SO) pin.
SO pin reports short-to-battery/supply or overcurrent condition.
Not reported.
SO pin reports output “OFF” open load condition.
Total device shutdown at V
recovery all outputs assume previous state or OFF based on the Overvoltage bit in the Global Shutdown /
Only the output experiencing an overtemperature shuts down. Output may auto-retry or remain OFF
according to the control bits in the Global Shutdown / Retry Control register.
Output will remain in current limit 0.9 A to 2.5 A until thermal limit is reached. When thermal limit is
reached, device will enter overtemperature shutdown. Output will operate as programmed in the Global
Shutdown/Retry Control register. Fault flag in SO Response word will be set.
