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. After 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

ADM6305D3ARJZ-RL7

model is

1.23 V, while in the case of

ADM6305D3ARJZ1-RL7

model, it is

0.4 V. The V

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

undervoltage threshold options for monitoring supply voltages

in increments between 2.5 V and 5 V. The

ADM6306

also

includes a manual reset input. Not all options are released for

sale as standard models. See the Ordering Guide for details.

The

ADM6305/ADM6306

RESET output remains valid as long

as V

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.
