7.4.3.1 Overview

The device creates fault events as outlined in Details On Generated Fault Events.

Table 7-7 Details On Generated Fault Events

Fault Event	Typical Reason	Channel Status Reporting ⁽¹⁾	Required User Response	Current status (non-latched) reported in	Event latched and reported in ⁽²⁾
VBAT Over Voltage Fault	VBAT above limit	'100' PROTECTIVE SHUTDOWN with AUTO RECOVERY State	Apply VBAT within spec	Power Fault Status Register	Power Fault Memory Register
VBAT Under Voltage Fault	VBAT below limit		Apply VBAT within spec
PVDD Over Voltage Fault	PVDD above limit		Apply PVDD within spec
PVDD Under Voltage Fault	PVDD below limit		Apply PVDD within spec
GVDD Fault	GVDD regulator fault
DVDD POR	DVDD voltage dropped below POR limit or initial device startup	'001' Hi-Z State	Write initial device configuration via I²C	N/A
Over Temperature SD - Channel	Channel temperature above limit	'101' PROTECTIVE SHUTDOWN State	Clear Fault	Temperature (OTSD) and Clock Sync Fault Status Register	Temperature (OTSD) and Clock Sync Fault Memory Register
Over Temperature SD - Global	Die temperature above limit	'101' PROTECTIVE SHUTDOWN State	Clear Fault	Temperature (OTSD) and Clock Sync Fault Status Register	Temperature (OTSD) and Clock Sync Fault Memory Register
Over Current Shut Down (OCSD) Event	Short to ground or short to power	'101' PROTECTIVE SHUTDOWN State	Clear Fault	N/A	Channel Over Current and DC Detection Fault Memory Register
DC Fault Event	DC voltage at device input				Channel Over Current and DC Detection Fault Memory Register
Load Current Fault Event	Shorted load				Channel Load Current Fault Memory Register
Invalid Clock Fault Event	Missing clock signal while device set up as clock slave	'100' PROTECTIVE SHUTDOWN with AUTO RECOVERY State	Apply sync clock signal within nominal range	Temperature (OTSD) and Clock Sync Fault Status Register	Temperature (OTSD) and Clock Sync Fault Memory Register
If 'OTSD auto recovery' is enabled in Miscellaneous Control Register 3:
Over Temperature SD- Channel	Channel temperature above limit	'100' PROTECTIVE SHUTDOWN with AUTO RECOVERY State	Cool down device	Temperature (OTSD) and Clock Sync Fault Status Register	Temperature (OTSD) and Clock Sync Fault Memory Register
Over Temperature SD - Global	Die temperature above limit	'100' PROTECTIVE SHUTDOWN with AUTO RECOVERY State	Cool down device	Temperature (OTSD) and Clock Sync Fault Status Register	Temperature (OTSD) and Clock Sync Fault Memory Register

1. See Channel State Report CH1, CH2 Register and Channel State Report CH3, CH4 Register for details.

2. Reading the memory register clears its content. This does not clear fault conditions.
