MAX813L, Microprocessor Supervisory Circuit, DIP-8

The MAX813L is a low-cost microprocessor supervisory circuit designed to improve the reliability and functionality of power supply monitoring in embedded systems. With an active-low reset output and an integrated power-fail detector, the MAX813L ensures smooth operation by resetting the microprocessor during power-down or brownout conditions. The watchdog timer provides an independent output that goes low if the watchdog input has not been toggled within 1.6 seconds, ensuring the system remains operational under unexpected conditions.

Operating with an input voltage range of 4.75V to 5.5V, this device offers precise monitoring with a reset threshold of 4.65V. The integrated manual reset input further enhances control and flexibility in system designs. Encased in a DIP-8 package, the MAX813L is ideal for compact designs requiring robust performance in power-critical applications like computers, controllers, and intelligent instruments.
