DESCRIPTION
Response Behavior
00-01 Not Used
During a fault, the device:
7:6 ^{• Pulls SALRT low}
10 Disable and Retry according to the setting in bits [5:3].
• Sets the related fault bit in the ^{11 Not Used}
status registers.
000 No Retry. The output remains disabled until the device is restarted.
5:3 Retry Setting
001-110 Not Used
111 Attempts to restart continuously, without limitation, until it is commanded OFF (by the
CONTROL pin or OPERATION command), bias power is removed, or another fault condition
causes the unit to shut down. The time between retries is set by bits [2:0].
2:0 Retry Time
111 The device will wait 80ms between disable and restart. 111 is the only valid entry for this field.
VIN_OV_WARN_LIMIT (57h)
Definition: Sets the V_IN overvoltage warning threshold as defined by the following table. In response to the OV_WARN_LIMIT being
exceeded, the device:
• Sets the NONE OF THE ABOVE and INPUT bits in STATUS_WORD
• Sets the VIN_OV_WARNING bit in STATUS_INPUT, and
• Notifies the host by setting the SALRT pin.
