CBM706P/706R/706S/706T/708R/708S/708T OPERATION INSTRUCTION FEATURES  GENERAL DESCRIPTION The Precision supply voltage monitor 2.63 V (CBM706P, CBM706R, CBM708R) CBM706T 2.93 V (CBM706S, CBM708S) /CBM708T CBM706P/CBM706R/CBM706S/ and the CBM708R/CBM708S microprocessor supervisory circuits are suitable for monitoring either 3 V 3.08 V (CBM706T, CBM708T) or 3.3 V power supplies.  100 µA quiescent current  200 ms reset pulse width  Debounced manual reset input (MR)  Independent watchdog timer power-up,  1.6 sec timeout (CBM706P, CBM706R, conditions. The CBM706S,CBM706T) operational with VCC Voltage monitor for power fail or low Independent watchdog monitoring circuitry is  The CBM706P/ CBM706R/ CBM706S/ CBM706T provide power supply monitoring circuitry that generate a reset output during Guaranteed RESET valid with VCC = 1 V  Superior upgrade for ADM706P/R/S/T, reset and brownout output as low remains as 1 V. also provided. This activates if the watchdog battery warning  power-down, input does not toggle within 1.6 sec. In addition, there is a 1.25 V threshold detector for a power fail warning, low battery ADM708R/S/T detection, or to monitor an additional power supply. An active low debounced MR input is APPLICATIONS also included. The CBM706R, CBM706S, and CBM706T  Microprocessor systems  Computers are identical except for the reset threshold  Controllers monitor levels, which are 2.63 V, 2.93 V, and  Intelligent instruments  Critical microprocessor monitoring  Battery operated systems  Portable instruments 3.08 V, respectively. The CBM706P is identical to the CBM706R in that the reset threshold is 2.63 V. It differs only in that it has an active high reset output. The provide CBM708R/CBM708S/CBM708T similar functio-nality as 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. 1 www.corebai.com CBM706P/706R/706S/706T/708R/708S/708T OPERATION INSTRUCTION FUNCTIONAL BLOCK DIAGRAMS *VOLTAGE REFERENCE = 2.63V (P/R), 2.93V (S), 3.08V (T) Figure 1.
