GENERAL DESCRIPTION
The ADM13307 is a triple voltage supervisor designed to
monitor up to three voltage levels in DSP and microprocessor-
based systems.
There are five models available, all of which feature a combina-
tion of internally pretrimmed undervoltage threshold options
for monitoring 1.8 V, 2.5 V, 3.3 V, and 5 V supplies. There are
also two adjustable input options with undervoltage thresholds of
either 0.6 V or 1.25 V.
The ADM13307-18, ADM13307-25, and ADM13307-33
models have two internally fixed thresholds and one externally
programmable threshold via a resistor string. The ADM13307-4
and ADM13307-5 offer one internally fixed threshold and two
externally programmable thresholds. See the Ordering Guide
for a list of all available options.
During power-up, RESET is asserted when the supply voltage
exceeds 1.1 V. The device then monitors the SENSEv input
pins and holds the RESET output low as long as the SENSEv
pins remain below the rising threshold voltage, V
IT+
.
Once the supplies monitored at the SENSEv inputs rise above
their associated thresholds, the reset signal remains low for the
reset timeout period before deasserting. Subsequently, if a volt-
age monitored by the SENSEv pins falls below its associated
falling input threshold voltage, V
IT−
, the RESET output asserts.

Figure 2.
The ADM13307 features both an active high RESET and an
active low RESET output.
The manual reset input of the ADM13307 can be used to initiate
a reset by means of an external push button or logic signal.
The ADM13307 is available in an 8-lead narrow body SOIC
package. The device operates over the extended industrial
temperature range of −40°C to +85°C.
