FET Short Fault Occurred
Indicates Potential FET Short was Detected When Measured Current Sense Voltage Exceeded 2mV
(code 0000111) While FET was Off
1 = FET was Shorted, 0 = FET is Good
D4
Board Present Changes State
Indicates that a Board was Inserted or Extracted When BD錚RST Changed State
1 = BD錚RST Changed State, 0 = BD錚RST Unchanged
D3
Power Bad Fault Occurred
Indicates Power was Bad When FB Went Low (C3 = 1)
While Gate-to-Source was High
1 = FB was Low and Gate was High, 0 = FB was Low and Gate was Low, or FB was High and Gate was
High or Low
D2
