PIN NAME FUNCTION
1 EN
Active-High Logic-Enable Input. Drive EN low to immediately deassert the output to its false state
(OUT = low) independent of V
IN
. With V
IN
above V
TH
, drive EN high to assert the output to its true
state (OUT = high) after the adjustable delay period. Connect EN to V
CC
, if not used.
2 GND Ground
3 IN
High-Impedance Monitor Input. Connect IN to an external resistive divider to set the desired monitor
threshold. The output changes state when V
IN
rises above 0.5V and when V
IN
falls below 0.495V.
4 OUT
Active-High Sequencer/Monitor Output. Open-drain (MAX16052) or push-pull (MAX16053). 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
(EN = high) after the capacitor-adjusted delay period. OUT is deasserted to its false state
(OUT = low) immediately after V
IN
drops below 0.495V or the enable input is in its false state
(EN = low). The MAX16052 open-drain output requires an external pullup resistor.
5 V
CC
Supply Voltage Input. Connect a 2.25V to 28V supply to V
CC
to power the device. For noisy systems,
bypass with a 0.1μF ceramic capacitor to GND.
6 CDELAY
Capacitor-Adjustable Delay Input. Connect an external capacitor (C
CDELAY
) from CDELAY to GND
to set the IN-to-OUT and EN-to-OUT delay period. For V
IN
rising, t
DELAY
= (C
CDELAY
x 4.0 x 106) +
30μs. For EN rising, t
PROP
= (C
CDELAY
x 4.0 x 10
6
) + 14μs.
