PRODUCTION DATA

Output voltage margin testing allows power designers to test the response of their system to across output voltage tolerance corners.

The MARGIN bits in the OPERATION command can be used to toggle the active channel between several states:

Table 7-5 Supported MARGIN settings

MARGIN bits	Description	Output voltage target	Voltage fault detection
0000b	Margin none	VOUT_COMMAND	Enabled
0101b	Margin low (act on faults)	VOUT_MARGIN_LOW	Enabled
0110b	Margin low (ignore on faults)	VOUT_MARGIN_LOW	Disabled
1001b	Margin high (act on faults)	VOUT_MARGIN_HIGH	Enabled
1010b	Margin high (ignore on faults)	VOUT_MARGIN_HIGH	Disabled
Other	Not supported/invalid data

Example procedure: voltage margin (ignore fault) testing

Write to the PAGE command to select the desired channel (E.g. 00h for channel A).
Write VOUT_COMMAND to the desired value during margin none operation.
Write VOUT_MARGIN_LOW to the desired value during margin low operation.
Write VOUT_MARGIN_HIGH to the desired value during margin high operation.
Write the ON_OFF_CONFIG command to ensure the device is configured to respect the OPERATION command.
Toggle to margin none operation. Write OPERATION to 80h.
Toggle to margin low (ignore fault) operation. Write OPERATION to 94h.
Toggle to margin high (ignore fault) operation. Write OPERATION to A4h.
