General Description
The MIC705, MIC706, MIC707, and MIC708 are inexpensive microprocessor supervisory circuits that monitor power supplies in microprocessor-based systems. The circuit functions include a watchdog timer, microprocessor reset, power-failure warning, and a debounced manual reset input.
FEATUREs
• Debounced manual reset input is TTL/CMOS compatible
• Reset pulse width: 200ms
• Watchdog timer: 1.6s (MIC705/706)
• 4.65V or 4.40V precision voltage monitor
• Early power-fail warning or low-battery detect
