Pin Descriptions
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 (LM3702 only).
RESET
Reset Logic Output. RESET is the inverse of RESET (LM3703 only).
C3
LLO
Low-Line Logic Output. Early Power-Fail warning output. Low when V
CC falls below VLLOT
(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.
B3
GND
Ground reference for all signals.
A2, A3, C2
NC
No Connect.
B2
NC
No Connect. Test input used at factory only. Leave floating.
