Programmable active high/low open drain latched output. Asserted when
programmed power supply is in a fault condition.
Programmable active high/low output asserted when all Fault conditions are
clear
Programmable active high/low open drain output signals when all
programmed power supplies are within the monitored limits and the MR signal
is inactive. RST has a programmable timeout period with options for
0.64/50/100/200ms.
Active low open drain I/O connected to LINK_B pin other SMT4504’s for
linked operation
Active low open drain I/O connected to LINK_A pin other SMT4504’s for
linked operation
Ground of the part
Active low open drain output. Asserted when the channel is tracking and
between track off and track on.

Do not drive FS# high.
Active high I/O signals the start of the power sequencing. When asserted the
part will sequence the supplies on and when de-asserted the part will
sequence the supplies off. Do not drive PWR_ON high.

Programmable active high/low write protect input. When asserted the
configuration registers are write protected and the write protect volatile
register is set.
