MR
Function
Manual-Reset input. When MR is less than V
MRT
(Manual Reset Threshold)
RESET/RESET is engaged.
Power Supply input.
Reset Logic Output. Pulses low for t
RP
(Reset Timeout Period) when triggered, and stays
low whenever V
CC
is below the reset threshold or when MR is below V
MRT
. It remains low
for t
RP
after either V
CC
rises above the reset threshold, or after MR input rises above
V
MRT
(LM3712 only).
Reset Logic Output. RESET is the inverse of RESET (LM3713 only).
Power-Fail Logic Output. When PFI is below V
PFT
PFO goes low; otherwise, PFO remains
high.
Watchdog Output. If no digital activity is detected on WDI (Watchdog Input) for a period
exceeding t
WD
, this output pulls low.
Ground reference for all signals.
Watchdog Input Transition Monitor: If no transition activity occurs for a period exceeding
t
WD
(Watchdog Timeout Period), reset is engaged.
Power-Fail Comparator Input. When PFI is less than V
PFT
(Power-Fail Reset Threshold),
the PFO goes low; otherwise, PFO remains high.
No Connect. Test input used at factory only. Leave floating.
