1 1 — — — — ENABLE
Active-High Logic-Enable Input. Drive ENABLE low to
immediately deassert the output to its false state (OUT =
low or OUT = high) independent of V
IN
. With V
IN
above
V
TH
, drive ENABLE high to assert the output to its true
state (OUT = high or OUT = low) after the adjustable
delay period (MAX689_A) or a 150ns propagation delay
(MAX689_P).
— — 1 1 1 1 ENABLE
Active-Low Logic-Enable Input. Drive ENABLE high to
immediately deassert the output to its false state (OUT =
low or OUT = high) independent of V
IN
. With V
IN
above
V
TH
, drive ENABLE low to assert the output to its true
state (OUT = high or OUT = low) after the adjustable
delay period (MAX689_A) or a 150ns propagation delay
(MAX689_P).
2 2 2 2 2 2 GND Ground
3 3 3 3 3 3 IN
High-Impedance Monitor Input. Connect IN to an
external resistive divider to set the desired monitored
threshold. The output changes state when V
IN
rises
above 0.5V and when V
IN
falls below 0.495V.
4 4 — — 4 4 OUT
Active-High Sequencer/Monitor Output, Push-Pull
(MAX6895/MAX6899) or Open-Drain (MAX6897). OUT
is asserted to its true state (OUT = high) when V
IN
is above V
TH
and the enable input is in its true state
(ENABLE = high or ENABLE = low) for the capacitor-
adjusted delay period. OUT is deasserted to its false
state (OUT = low) immediately after V
IN
drops below
V
TH
- 5mV or the enable input is in its false state
(ENABLE = low or ENABLE = high). The open-drain
version requires an external pullup resistor.
— — 4 4 — — OUT
Active-Low Sequencer/Monitor Output, Push-Pull
(MAX6896) or Open-Drain (MAX6898). OUT is asserted
to its true state (OUT = low) when V
IN
is above V
TH
and the enable input is in its true state (ENABLE = high
or ENABLE = low) after the CDELAY adjusted timeout
period. OUT is deasserted to its false state (OUT =
high) immediately after V
IN
drops below V
TH
- 5mV or
the enable input is in its false state (ENABLE = low or
ENABLE = high). The open-drain version requires an
external pullup resistor.
5 6 5 6 5 6 CDELAY
Capacitor-Adjustable Delay. Connect an external
capacitor (C
CDELAY
) from CDELAY to GND to set the
IN to OUT (and ENABLE to OUT or ENABLE to OUT
for A version devices) delay period. t
DELAY
= (C
CDELAY
x 4.0 x 10
6
) + 40µs. There is a fixed short delay (40µs,
typ) for the output deasserting when V
IN
falls below
V
TH
.
6 5 6 5 6 5 V
CC
Supply Voltage Input. Connect a 1.5V to 5.5V supply
to V
CC
to power the device. For noisy systems, bypass
with a 0.1µF ceramic capacitor to GND.
