GENERAL DESCRIPTION

The ADM705/ADM706/ADM707/ADM708 microprocessor

supervisory circuits are suitable for monitoring 5 V power

supplies/batteries and microprocessor activity.

The ADM705/ADM706 provide power-supply monitoring

circuitry that generate a reset output during power-up, power-

down, and brownout conditions. The reset output remains

operational with VCC as low as 1 V. Independent watchdog

monitoring circuitry is also provided. This is activated if the

watchdog input has not been toggled within 1.60 sec.

In addition, there is a 1.25 V threshold detector to warn of

power failures, to detect low battery conditions, or to monitor an

additional power supply. An active low, debounced manual reset

input (MR) is also included.

The ADM705 and ADM706 are identical except for the reset

threshold monitor levels, which are 4.65 V and 4.40 V, respectively.

The ADM707 and ADM708 provide a similar functionality to

the ADM705 and ADM706 and only differ in that a watchdog

timer function is not available. Instead, an active high reset

output (RESET) is available as well as the active low reset output

(RESET). The ADM707 and ADM708 are identical except for

the reset threshold monitor levels, which are 4.65 V and 4.40 V,

respectively.

All devices are available in narrow 8-lead PDIP and 8-lead SOIC

packages.

CIRCUIT INFORMATION

POWER FAIL RESET OUTPUT

RESET is an active low output that provides a reset signal to

the microprocessor whenever the VCC input is below the reset

threshold. An internal timer holds RESET low for 200 ms after

the voltage on VCC rises above the threshold. This functions as a

power-on reset signal for the microprocessor. It allows time for

both the power supply and the microprocessor to stabilize after

power-up. The RESET output is guaranteed to remain valid (low)

with VCC as low as 1 V. This ensures that the microprocessor is

held in a stable shutdown condition as the power supply voltage

ramps up.

In addition to RESET, an active high RESET output is also available

on the ADM707/ADM708. This is the complement of RESET

and is useful for processors requiring an active high reset signal.

MANUAL RESET

The manual reset input (MR) allows other reset sources, such as

a manual reset switch, to generate a processor reset. The input is

effectively debounced by the timeout period (200 ms typically).

The MR input is TTL-/CMOS-compatible, so it can also be driven

by any logic reset output.

WATCHDOG TIMER (ADM705/ADM706)

The watchdog timer circuit can monitor the activity of the micro-

processor to check that it is not stalled in an indefinite loop. An

output line on the processor toggles the watchdog input (WDI)

line. If this line is not toggled within the timeout period (1.60 sec),

then the watchdog output (WDO) goes low. The WDO can be

connected to a nonmaskable interrupt (NMI) on the processor;

therefore, if the watchdog timer times out, an interrupt is gen-

erated. The interrupt service routine then rectifies the problem.

If a RESET signal is required when a timeout occurs, the WDO

must connect to the manual reset input (MR).

The watchdog timer is cleared by either a high to low or a low to

high transition on WDI. It is also cleared by RESET going low;

therefore, the watchdog timeout period begins after RESET

goes high.

When VCC falls below the reset threshold, WDO is forced low,

whether or not the watchdog timer has timed out. Normally, this

generates an interrupt, but it is overridden by RESET going low.

The watchdog monitor can be deactivated by floating the WDI.

The WDO can then be used as a low line output because it goes

low only when VCC falls below the reset threshold.

POWER FAIL COMPARATOR

The power fail comparator is an independent comparator that

can monitor the input power supply. The comparator inverting

input is internally connected to a 1.25 V reference voltage. The

noninverting input is available at the PFI input. This input can

monitor the input power supply via a resistive divider network.

When the voltage on the PFI input drops below 1.25 V, t h e

comparator output (PFO) goes low, indicating a power failure. For

early warning of power failure, the comparator monitors the

preregulator input by choosing an appropriate resistive divider

network. The PFO output can interrupt the processor so a

shutdown procedure is implemented before power is lost.

As the voltage on the PFI pin is limited to VCC + 0.3 V, i t i s

recommended to connect the PFI pin with a Schottky diode to

the RESET pin as shown in Figure 15. This helps clamping the

PFI pin voltage during device power up and operation.

Adding Hysteresis to the Power Fail Comparator

For increased noise immunity, hysteresis can be added to the

power fail comparator. Because the comparator circuit is

noninverting, hysteresis can be added by connecting a resistor

between the PFO output and the PFI input as shown in Figure 16.

When PFO is low, Resistor R3 sinks current from the summing

junction at the PFI pin. When PFO is high, Resistor R3 sources

current into the PFI summing junction. This results in differing

trip levels for the comparator. Further noise immunity can be

achieved by connecting a capacitor between PFI and GND. The

The ADM705/ADM706/ADM707/ADM708 are guaranteed to

provide a valid reset level with VCC as low as 1 V (see the Typical

Performance Characteristics section). As VCC drops below 1 V,

the internal transistor does not have sufficient drive to hold the

voltage RESET at 0 V. A pull-down resistor can connect externally,

as shown in Figure 17, to hold the line low if required.

APPLICATIONS INFORMATION

A typical application circuit is shown in Figure 18. The un-

regulated dc input supply is monitored using PFI via the resistive

divider network. Resistor R1 and Resistor R2 must be selected

so when the supply voltage drops below the desired level (such

as 8 V), the voltage on PFI drops below the 1.25 V threshold,

thereby generating an interrupt to the microprocessor. Monitoring

the preregulator input provides additional time to execute an

orderly shutdown procedure before power is lost.

Figure 18. Typical Application Circuit

Microprocessor activity is monitored using WDI. This is driven

using an output line from the processor. The software routines

toggle this line at least once every 1.60 seconds. If a problem occurs

and this line is not toggled, WDO goes low and a nonmaskable

interrupt is generated. This interrupt routine can clear the problem.

If, in the event of inactivity on the WDI line, a system reset is

required, WDO must connect to MR as shown in Figure 19.

MONITORING ADDITIONAL SUPPLY LEVELS

It is possible to use the power fail comparator to monitor a

second supply as shown in Figure 20. The two sensing resistors,

R1 and R2, are selected so the voltage on PFI drops below 1.25 V at

the minimum acceptable input supply. PFO can connect to MR so

a reset is generated when the supply drops out of tolerance. In

this case, if either supply drops out of tolerance, a reset is generated.

MICROPROCESSOR WITH BIDIRECTIONAL RESET

To prevent contention for microprocessors with a bidirectional

reset line, a current limiting resistor must be inserted between

the ADM705/ADM706/ADM707/ADM708 RESET output pin

and the microprocessor RESET pin. This limits the current to a

safe level if there are conflicting output reset levels. A suitable

resistor value is 4.7 kΩ. If the reset output is required for other

uses, it must be buffered, as shown in Figure 21.
