Pin Description
Bump No.
Name
Function
A1
MR
Manual-Reset input. When MR is less than V
MRT (Manual Reset Threshold)
RESET/RESET is engaged.
B1
V
CC
Power Supply input.
C1
RESET
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 VMRT. It remains low
for t
RP after either VCC rises above the reset threshold, or after MR input rises above
V
MRT (LM3712 only).
RESET
Reset Logic Output. RESET is the inverse of RESET (LM3713 only).
C2
PFO
Power-Fail Logic Output. When PFI is below V
PFT PFO goes low; otherwise, PFO remains
high.
C3
WDO
Watchdog Output. If no digital activity is detected on WDI (Watchdog Input) for a period
exceeding t
WD, this output pulls low.
B3
GND
Ground reference for all signals.
A3
WDI
Watchdog Input Transition Monitor: If no transition activity occurs for a period exceeding
t
WD (Watchdog Timeout Period), reset is engaged.
A2
PFI
Power-Fail Comparator Input. When PFI is less than V
PFT (Power-Fail Reset Threshold),
the PFO goes low; otherwise, PFO remains high.
B2
NC
No Connect. Test input used at factory only. Leave floating.
