GENERAL DESCRIPTION

1.23 V, while in the case of ADM6305DxARJZ1 model, it is

0.4 V. The V_CCinput of the ADM6305 is not a monitored input.

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.

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.

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.

output remains valid as long

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

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.
