CBM705/CBM706/CBM707/CBM708 OPERATION INSTRUCTION FEATURES GENERAL DESCRIPTION  Guaranteed RESET valid with VCC = 1V The CBM705, CBM706, CBM707, CBM708  190 μA quiescent current microprocessor supervisory circuits  Precision supply voltage monitor suitable monitoring 5V supplies/batteries 4.65 V (CBM705/CBM707) 200 ms reset pulse width  Debounced TTL/CMOS manual reset and power microprocessor activity. 4.40 V (CBM706/CBM708)  for are The CBM705/ power-supply CBM706 monitoring provide circuitry that generate a reset output during power-up, input (MR) power-down, and brownout conditions. The Independent watchdog timer reset output remains operational with VCC as (CBM705/CBM706) low as 1V. Independent watchdog monitoring  1.60 sec timeout (CBM705/CBM706) circuitry is also provided. This is activated if  Active high reset output  the watchdog input has not been toggled within 1.60 sec. (CBM707/CBM708)  In addition, there is a 1.25V threshold Voltage monitor for power fail or low detector to warn of power failures, to detect battery warning  low battery conditions, or to monitor an Superior upgrade for ADM705 to additional power supply. An active low, ADM708 debounced manual reset input ( MR ) is also included. APPLICATIONS  Microprocessor systems  Computers  Controllers  Intelligent instruments  Critical microprocessor supply 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 monitoring 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. 1 www.corebai.com PDF
