ADI Introduces a New Family of Ultralow Power Supervisory Circuits

The ADM6326, ADM6328, ADM6346, and ADM6348 are ultralow power microprocessor supervisory circuits
suited to monitoring the power supplies in portable microprocessor-based applications. This new family of
ultralow power supervisory circuits extend the battery life of portable devices by only consuming 500 nA (typ)
supply current while maximizing product reliability through robust power supply monitoring.

Simple Reset/Power-On Reset

Analog Devices offers an extensive range of reset generator circuits
designed for use in microprocessor-based systems to monitor power
supply voltage levels from 1.8 V to 5 V. Their reset output signals are
asserted whenever the supply voltage falls below a preset threshold level.

A number of these devices offer a manual reset input, allowing a user
to safely reset a microprocessor system by means of an external push­button switch.

Watchdog Supervisory Circuits

Microprocessors need to be reset when code execution errors occur, as well

when supply voltages fall to invalid levels. A watchdog function can detect

as
code execution errors by monitoring logic transitions on a microprocessor’s
output pin. If the transitions are not frequent enough, the watchdog circuit

initiates a reset, taking the microprocessor out of its invalid state.

Many ADI reset generator watchdog circuits also feature a power-fail
detection

comparator that asserts an active low signal when the unregulated
power supply voltage falls below a predetermined level. This power-fail
output can be used to generate a nonmaskable interrupt, which allows the
microprocessor to implement a shutdown procedure before power is lost.

Multivoltage Monitors

Analog Devices offers a portfolio of multivoltage monitors suited to
monitoring two, three, or four supplies. There are several device families
offering combinations of positive and negative pretrimmed thresholds and
user adjustable inputs, with some including a watchdog timer function.
With up to twice the threshold accuracy over temperature of competitive
parts, these new ADI products offer the ability to monitor emerging low
voltage core requirements and, therefore, maximize system protection.

POWER GOOD

In this example a 1 V regulated supply produces a voltage that varies between 0.97 V and 1.03 V. The core voltage acceptable is 1 V (±5%),
that is, 0.95 V to 1.05 V. This results in a range of just 2.0% for UV monitoring. The high ±0.8% accuracy of the ADM1184 along with ±0.1%
accurate resistors in the voltage divider at VINx combine to allow accurate monitoring of the undervoltage level within this 2% range.

The ADM12914 detects overvoltage and undervoltage (OV/UV) conditions
with 1.5 times the accuracy (±0.8% over temperature) of competing
supervisory circuits.

This translates into improved system operation as the new supervisory
IC prevents power supplies from slipping out of range in medical
ultrasound, telecommunications equipment, and other applications.

This is especially important in today’s power supply systems, which
often operate at below 1 V and where an overvoltage condition could
cause catastrophic system failures. The ADM2914/ADM12914 also
includes an input-supply shunt regulator that enables the device to
be run off of higher voltage supplies, including 12 V operation in
communications infrastructure equipment and lithium-ion batteries
used in hybrid vehicles.

allow user programmability of the voltage thresholds to be monitored to
a minimum of 0.6 V, with ±0.8% accurate comparators ensuring voltage

ADM1186: Quad Channel Up and Down Power Supply Sequencers and Monitors

The ADM1186 family provides the same high ±0.8% monitoring accuracy as the ADM1184 and ADM1185, but add a number of features to provide
designers with additional functionality and flexibility. The ADM1186 are able to perform up and down power supply sequencing, and in the case of the
ADM1186-1, multiple devices can be cascaded together to sequence up and down 8, 12, 16, or even more supplies.

Dedicated capacitor programmable timing pins allow the time delays
between supplies to be easily controlled without the need to place a
capacitor on the supply rail monitoring pin. This allows the sequencing
time delay and fault response time of the device to be controlled
independently and accurately. In addition to the sequence time delays,
a programmable blanking time delay is provided to allow the designer
to set a maximum time limit for a supply to rise above its undervoltage
threshold after being enabled.

Features

•Monitors four supplies via ±0.8% accurate

comparators

•Powered from 2.7 V to 5.5 V on the VCC pin

SEQUENCE

•Digital core supports up and down supply sequencing

CONTROL
