Product details

What the MAX6372KA+T is and where it fits

The Maxim Integrated MAX6372KA+T is a single-channel watchdog supervisor IC in an SOT-23-8 package, delivering an active-low reset output from a push-pull, totem-pole stage. It monitors one voltage rail with an adjustable/selectable threshold, and its reset timeout is also adjustable — so you set both the trip point and the watchdog period to match the processor or ASIC it is guarding. The -40°C to 125°C operating range covers industrial and automotive under-hood environments, making it a fit for motor drives, engine ECUs, and outdoor telecom gear where a hung system needs a hard, fast reset.

Adjustable threshold and timeout — what that means for the BOM

Both the voltage threshold and the reset timeout are adjustable/selectable on this part. That means one MAX6372KA+T can serve across multiple rail voltages in a design — you size the resistor divider for the monitored rail, set the watchdog period with a capacitor, and the same P/N covers the rail the micro needs.

Lifecycle and sourcing reality

The MAX6372KA+T carries an Active product status and is ROHS3 compliant.

Frequently asked questions

Does MAX6372KA+T support adjustable reset timeout?

Yes. The reset timeout is adjustable/selectable, so you set the watchdog period with an external capacitor to match the processor's required reset pulse width.

What is the closest pin-compatible alternative to MAX6372KA+T?

The MAX6371 is a direct sibling in the same family. Both are single-channel watchdog supervisors in SOT-23-8 with push-pull outputs and adjustable timeout. The primary difference is the reset output polarity — the MAX6372KA+T delivers an active-low reset, while the MAX6371 uses an active-high output. Verify the logic level your processor expects before substituting.

What is MAX6372KA+T's listed type?

The device type is a Watchdog Circuit — a supervisor IC that monitors a voltage rail and asserts a reset if the system fails to strobe the watchdog input within the programmed timeout window.

What is MAX6372KA+T's listed reset?

The reset output is Active Low, meaning the reset pin goes low when a fault is detected (voltage below threshold or watchdog timeout). It returns high after the reset timeout period expires.
