Product details

What this watchdog circuit does and where it fits

The MAX6374KA+T from Analog Devices is a single-channel watchdog supervisory circuit in a SOT-23-8 package. It monitors system activity and asserts a reset output when the watchdog input is not toggled within the programmed timeout window. The reset output is active low, push-pull/totem pole, so it drives directly into the reset pin of most MCUs, DSPs, or SoCs without an external pull-up resistor. The timeout period and voltage threshold are both adjustable or selectable via external components or pin strapping, giving the designer control over the monitoring window without changing the board layout. Rated for -40°C to 125°C, this part suits industrial motor drives, automotive under-hood modules, and outdoor telecom equipment where the ambient temperature can swing beyond commercial limits.

Frequently asked questions

How do I set the adjustable timeout on MAX6374KA+T?

The reset timeout is adjustable or selectable via an external capacitor or pin configuration. The exact capacitor value and pin connections are detailed in the datasheet; the part does not require a fixed external resistor network for timeout programming.
