PROGRAMMING THE SFD'S ON THE SMBUS

The details of using the SMBus are described later, but
the register names associated with the Supply Fault Detec-
tor blocks, the bitmap of those registers, and the function
of each of the bits is described in the following tables.
The tables show how to set up UV threshold, UV hyster-
esis, OV threshold, OV hysteresis, glitch filtering and
fault type for each of the SFD's on the ADM1060.
Description
Overvoltage Threshold for Bipolar Voltage SFD1 (BS1SFD)
Digital Hysteresis on OV threshold for BS1SFD
Undervoltage Threshold for BS1SFD
Digital Hysteresis on UV threshold for BS1SFD
Glitch filter, Range and Fault Type select for BS1SFD
Overvoltage Threshold for Bipolar Voltage SFD2 (BS2SFD)
Digital Hysteresis on OV threshold for BS2SFD
Undervoltage Threshold for BS2SFD
Digital Hysteresis on UV threshold for BS2SFD
Glitch filter, Range and Fault Type select for BS2SFD
Overvoltage Threshold for High Voltage SFD
Digital Hysteresis on OV threshold for HVSFD
Undervoltage Threshold for HVSFD
