MAXIM INTEGRATED / ANALOG DEVICES DS1814BR5TR Microprocessor Monitor
The DS1814 and DS1819 are microprocessor monitors designed to ensure reliable system operation by supervising power supply, execution, and external override. These devices feature power-fail detection, pushbutton reset, and optional watchdog timer functions, making them suitable for microcontroller-based systems. The DS1814 operates at 5V, while the DS1819 supports 3.3V. They debounce pushbuttons, generate minimum 140ms reset pulses upon power failure or manual reset, and have configurable watchdog timeout of 1.12 seconds. Compact and pin-compatible, they eliminate external components for robust system protection.
