Working Principles

The MAX6897PALT/GG8 continuously monitors the system voltage and compares it to the adjustable reset threshold. If the voltage falls below the threshold or the watchdog timer times out, the device asserts the reset signal. The power-fail comparator detects an impending power failure and triggers the power-fail output. The manual reset input allows for external control over the reset function.

Detailed Application Field Plans

The MAX6897PALT/GG8 is commonly used in embedded systems, industrial control systems, automotive electronics, and portable devices where reliable voltage monitoring and reset generation are critical for system stability.
