Key Featrues
Power-Fail Detection: The DS1812 and DS1817 EconoResets feature power-fail detection, which ensures the system is reset during power transients or out-of-tolerance conditions. This enhances system reliability by preventing erratic behavior during unstable power conditions.
150ms Stabilization Pause: After power returns to tolerance, the device holds the reset signal for 150ms to allow the system to stabilize. This feature ensures proper initialization and reduces the risk of system errors during power-up.
Push-Pull Active High Reset: The push-pull active high reset output provides a strong, clean signal without requiring external pull-up resistors. This simplifies circuit design and improves signal integrity in applications requiring precise reset timing.
Low Quiescent Current: With a maximum quiescent current of 40µA, the device minimizes power consumption, making it suitable for battery-powered or energy-efficient applications where power savings are critical.
Wide Operating Range: The device operates across a wide temperature range of -40°C to +85°C and supports 5V with 5%, 10%, or 15% tolerance. This versatility makes it suitable for a variety of industrial and consumer applications in harsh environments.
