Fault Detect & Status Register

[3:0] – These 4 level triggered bits indicate the current state of the

comparators monitoring the V1MON and V2MON input pins.

[0] – A ‘1’ indicates V2MON input < V2MON OFF Threshold

[1] – A ‘1’ indicates V2MON input > V2MON ON Threshold

[2] – A ‘1’ indicates V1MON input < V1MON UV Threshold

[3] – A ‘1’ indicates V1MON input > V1MON OV Threshold

[6:4] – These are Fault Detection bits can be decoded to indicate one or

more conditions were present when a SHDN event occurred. These

bits are edge triggered.

000 – None

001 – V1MON UV only

010 – V1MON OV only

011 – Never Occur

100 – V2MON Below OFF only

101 – V1MON UV AND V2MON Below OFF Both Occur

110 – V1MON OV AND V2MON Below OFF Both Occur

0x00
