The MAX16052/MAX16053 are a family of small, low-

power, high-voltage monitoring circuits with sequenc-

ing capability. These miniature devices offer very wide

flexibility with an adjustable voltage threshold and an

external capacitor-adjustable time delay. These

devices are ideal for use in power-supply sequencing,

reset sequencing, and power switching applications.

Multiple devices can be cascaded for complex

sequencing applications.

A high-impedance input (IN) with a 0.5V threshold

allows an external resistive divider to set the monitored

threshold. The output (OUT) asserts high when the

input voltage rises above the 0.5V threshold and the

enable input (EN) is asserted high. When the voltage at

IN falls below 0.495V or when the enable input is

deasserted (EN = low), the output deasserts (OUT =

low). The MAX16052/MAX16053 provide a capacitor

programmable delay time from when the voltage at IN

rises above 0.5V to when the output is asserted.

The MAX16052 offers an active-high open-drain output

while the MAX16053 offers an active-high push-pull out-

put. Both devices operate from a 2.25V to 16V supply

voltage and feature an active-high enable input. The

MAX16052/MAX16053 are available in a tiny 6-pin

SOT23 package and are fully specified over the auto-

motive temperature range (-40°C to +125°C).
