CBM706P/706R/706S/706T/708R/708S/708T

OPERATION INSTRUCTION

FEATURES

GENERAL DESCRIPTION



Precision supply voltage monitor

2.63 V (CBM706P, CBM706R, CBM708R)

The CBM706P/ CBM706R/ CBM706S/

CBM706T and the CBM708R/ CBM708S /

CBM708T microprocessor supervisory circuits

are suitable for monitoring either 3V or 3.3V

power supplies.

2.93 V (CBM706S, CBM708S)

3.08 V (CBM706T, CBM708T)

100µA quiescent current

200ms reset pulse width



The CBM706P/ CBM706R/ CBM706S/

CBM706T provide power supply monitoring

circuitry that generate a reset output during

power-up, power-down, and brownout

conditions. The reset output remains

operational with V_CCas low as 1V.

ꢀꢀꢀꢀ

Debounced manual reset input (MR)

Independent watchdog timer

1.6 sec timeout (CBM706P, CBM706R,

CBM706S, CBM706T)

Independent

watchdog

monitoring



Voltage monitor for power fail or low

battery warning

circuitry is also provided. This activates if the

watchdog input does not toggle within 1.6

sec.

ꢀꢀꢀꢀꢀꢀꢀ



Guaranteed RESET valid with VCC = 1 V

Superior upgrade for ADM706P/R/S/T,

ADM708R/S/T

In addition, there is a 1.25V threshold

detector for a power fail warning, low battery

detection, or to monitor an additional power

supply. An active low debounced MR input is

also included.



Microprocessor systems

Computers

The CBM706R, CBM706S, and CBM706T

are identical except for the reset threshold

monitor levels, which are 2.63V, 2.93V, and

3.08V, respectively. The CBM706P is identical

to the CBM706R in that the reset threshold is

2.63V. It differs only in that it has an active

high reset output.



Controllers

Intelligent instruments

Critical microprocessor monitoring

Battery operated systems

Portable instruments

The CBM708R/ CBM708S/ CBM708T

provide

similar

functio-nality

the

CBM706R/CBM706S/CBM706T and only differ

in that a watchdog timer function is not

available. Instead, an active high reset output

(RESET) is provided in addition to the active

ꢀꢀꢀꢀꢀꢀꢀ

low (RESET) output.

All devices are available in narrow 8-lead

PDIP and 8-lead SOIC packages.
