MAX813 timer circuit

The MAX813 is a microprocessor supervisory circuit designed to monitor power supplies and provide reliable system reset functionality. It integrates multiple functions, including a precision voltage reference, a reset timer, and a watchdog timer, into a single package. The MAX813 ensures that microprocessor systems start up correctly and operate reliably by generating reset signals during power-up, power-down, and brownout conditions, as well as providing a watchdog timer to guard against system lockup.

Key Features:

• Precision supply voltage monitoring
• Manual reset input
• Watchdog timer to prevent system lockup
• Reset output for power-up, power-down, and brownout conditions
• Low power consumption
• Compact 8-pin DIP/SOIC package
• Active-low and active-high reset outputs

Technical Specifications:

• Supply Voltage (VCC): 4.5V to 5.5V
