B1 — — RESET
Active-Low Push-Pull Reset Output. RESET changes from high to
low when V
CC drops below the detector threshold (V TH ) or MR is
pulled low. RESET remains low for the reset timeout period after V CC
exceeds V TH and MR is high. When MR is low, RESET is low.
— B1 — RESET
Active-High Push-Pull Reset Output. RESET changes from low to
high when V
CC drops below the detector threshold (V TH ) or MR is
pulled low. RESET remains high for the reset timeout period after V CC
exceeds V TH and MR is high. When MR is low, RESET is high.
— — B1 RESET
Active-Low Open-Drain Reset Output. RESET changes from high-
impedance to active-low when V
CC drops below the detector thresh-
old (V TH ) or MR is pulled low. RESET remains low for the reset timeout
period after V CC exceeds the reset threshold and MR is high. When
MR is low, RESET is low.
A2 A2 A2 V CC Supply Voltage and Input for the Reset Threshold Monitor
B2 B2 B2 MR
Active-Low Manual-Reset Input. Drive low to force a reset. Reset
remains active as long as MR is low and for the reset timeout period (if
applicable) after MR is driven high. MR has an internal pullup resistor
connected to V
CC, and may be left unconnected if not used.
