GENERAL DESCRIPTION

The CBM705, CBM706, CBM707, CBM708

microprocessor

supervisory

circuits

are

suitable

for

monitoring

5V

power

supplies/batteries

and

microprocessor

activity.

The

CBM705/

CBM706

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 1V. 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 1.25V 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 CBM705 and CBM706 are identical

except for the reset threshold monitor levels,

which are 4.65V and 4.40V, respectively.

The CBM707 and CBM708 provide a

similar functionality to the CBM705 and

CBM706 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 CBM707 and CBM708 are identical except

for the reset threshold monitor levels, which

are 4.65V and 4.40V, respectively.

All devices are available in narrow 8-lead

SOIC packages.
