MR
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
(LM3704 only).
Reset Logic Output. RESET is the inverse of RESET (LM3705 only).
Power-Fail Logic Output. When PFI is below V
PFT
, PFO goes low; otherwise, PFO
remains high.
Low-Line Logic Output. Early Power-Fail warning output. Low when V
CC
falls below V
LLOT
(Low-Line Output Threshold). This output can be used to generate an NMI (Non-Maskable
Interrupt) to provide an early warning of imminent power-failure.
Ground reference for all signals.
No Connect.
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.
