MAX6751KA46-T

Supervisors Overview

The MAX6751KA46-T is a low-power microprocessor supervisory circuit from Analog Devices/Maxim Integrated, designed to monitor single system supply voltages. It features a factory-set reset threshold of 4.625V with an adjustable range capability. The device provides capacitor-adjustable reset and watchdog timeout delays, ensuring reliable operation against power-supply transients. It operates within a supply voltage range of 1.575V to 5V and maintains a typical supply current of 3.7µA. The output is available in open-drain configuration, housed in an 8-pin SOT-23 package.

Supervisors Feature Summary

• Capacitor-adjustable reset and watchdog timeout delays for flexible timing control
• Factory-set reset threshold options with high accuracy and transient immunity
• Low quiescent supply current suitable for battery-powered applications

Supervisors Applications

• Microprocessor monitoring in embedded controllers
• Portable equipment and battery-powered computers
• Automotive intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the KA46 designation corresponds to the 4.625V threshold variant. Check for RoHS compliance status and lead times due to potential limited availability or obsolescence notices associated with Maxim Integrated product lines.

Supervisors Selection Notes

Select this component when a fixed 4.625V threshold is required alongside customizable timeout periods via external capacitors. Ensure the open-drain output compatibility matches the target microprocessor reset input requirements. Verify that the operating temperature range meets the environmental conditions of the intended application.

Supervisors Part Context

This part belongs to the MAX6746–MAX6753 family of low-power µP supervisory circuits. These devices are engineered for maximum adjustability in reset and watchdog functions while monitoring single or dual supply voltages. The family supports various threshold options and output configurations to accommodate diverse system design constraints.

Supervisors Replacement Considerations

Consider MAX6751KA46+ as a non-tape equivalent if reel packaging is not strictly required. Other family members like MAX6750 or MAX6752 may offer push-pull outputs or dual-channel monitoring if system requirements change.
