CBM705A 电压监控微处理器监控电路

The CBM705A, CBM706A, CBM707A, CBM708Amicroprocessor supervisory circuits are suitable for monitoring 5V power supplies/batteries and microprocessor activity. The CBM705A/CBM706A 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 CBM705A and CBM706A are identical except for the reset threshold monitor levels, which are 4.65V and 4.40V, respectively. The CBM707A and CBM708A provide a similar functionality to the CBM705A and CBM706A 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 CBM707A and CBM708A 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.
