GENERAL DESCRIPTION
The ADM6305/ADM6306 are dual voltage supervisors
designed to monitor two supplies and provide a reset signal to
DSP- and microprocessor-based systems. Low supply current
and a small form factor make these devices suitable for portable
and battery-operated applications.
If a monitored power supply voltage falls below the minimum
voltage threshold, a single active low output asserts triggering a
system reset. Once all voltages rise above the selected threshold
level, the reset signal remains low for the reset timeout period.
Four reset timeout options are available.
The ADM6305 monitors two supplies via two adjustable
resistor-programmable undervoltage reset inputs. Both RST
IN1 and RST IN2 have a reset threshold of either 0.4 V or
1.23 V depending on the particular model; that is, the RST IN1
and RST IN2 threshold of the ADM6305DxARJZ model is
Rev. A

1.23 V, while in the case of ADM6305DxARJZ1 model, it is
0.4 V. The V CC input of the ADM6305 is not a monitored input.
The ADM6306 has one adjustable undervoltage reset input,
RST IN, which features a choice of reset threshold, 0.4 V or
1.23 V (see the Ordering Guide for more information). The
ADM6306 incorporates a variety of internally pretrimmed V CC
undervoltage threshold options for monitoring supply voltages
in increments between 2.5 V and 5 V. The ADM6306 also
includes a manual reset input.
The ADM6305/ADM6306 RESET output remains valid as long
as V CC exceeds 0.9 V.
The ADM6305/ADM6306 are available in a 5-lead SOT-23
package. These devices are specified over the temperature range
of ?40°C to +125°C.
