MAX6370KA/V+T

Supervisors Overview

The MAX6370KA/V+T is a pin-selectable watchdog timer and voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 2.5V to 5.5V and features an adjustable threshold voltage for monitoring a single input. The device utilizes an SOT-23-8 surface-mount package and provides an open-drain output type without manual reset functionality. It includes a built-in watchdog timer with a fixed reset delay time of 180 ms. The component supports a working supply current of 10 uA and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Pin-selectable configuration allows flexible integration of watchdog timer and supervisory functions.
• Integrated watchdog timer ensures system reliability through automated timeout detection.
• Low power consumption design suitable for battery-operated or energy-efficient applications.

Supervisors Applications

• Microprocessor system supervision
• Embedded controller reset circuits
• Industrial control systems requiring watchdog protection

Supervisors Procurement Notes

Verify the specific suffix (K or V) against the official datasheet to confirm pin selection options, as these determine the internal configuration of the watchdog and supervisor functions. Ensure the ordering part number matches the required package variant and that the supplier provides valid traceability documentation for this discontinued or limited-stock item.

Supervisors Selection Notes

Select this component when a single IC solution is needed for both voltage supervision and watchdog timing in space-constrained designs. The SOT-23-8 package offers a compact footprint compared to larger SOIC options. Consider the 180ms fixed reset delay and open-drain output characteristics to ensure compatibility with the target microprocessor's reset requirements and bus logic levels.

Supervisors Part Context

This part belongs to the MAX6369-MAX6374 series of pin-selectable watchdog timers. These devices are designed to replace multiple discrete components by integrating supervisor and watchdog functions into a single chip. The series is characterized by low power operation and flexible configuration options via external pins, catering to various microprocessor architectures.
