Microprocessor Supervisory Circuits
General Description
The MAX696, MAX697 supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery-control functions in microprocessor (μP) systems. These include μP reset and backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure warning. The MAX696, MAX697 significantly improve system reliability and accuracy compared to that obtained with separate ICs or discrete components.
The MAX696 and MAX697 are supplied in 16-pin packages and perform six functions:
1) A reset output during power-up, power-down, and brownout conditions. The threshold for this “lowline” reset is adjustable by an external voltagedivider.
2) A reset pulse if the optional watchdog timer has not been toggled within a specified time.
3) Individual outputs for low-line and watchdog fault conditions.
4) The reset time may be left at its default value of 50ms, or may be va.
