MAX6753KA44

Supervisors Overview

The MAX6753KA44 is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides reset and watchdog timer functions in an SOT-23-8 package. The device features an adjustable reset threshold voltage, allowing for flexible system monitoring. It operates within a supply voltage range of 1.0 V to 5.5 V. Key electrical characteristics include a typical watchdog timeout period and precise reset delay timing. The component supports open-drain or open-collector outputs and includes a manual reset input.

Supervisors Feature Summary

• Adjustable reset threshold voltage for customizable system supervision
• Integrated watchdog timer with programmable timeout interval
• Manual reset input capability for external control
• Open-drain or open-collector output configuration

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify the specific suffix 'KA44' to confirm the adjustable reset threshold voltage setting. Ensure the package type matches the required SOT-23-8 footprint. Confirm RoHS compliance status if environmental regulations apply to your assembly process. Check for lead-free markings on the component body or datasheet specifications to ensure material compatibility with soldering processes.

Supervisors Selection Notes

Select this component when an adjustable reset threshold is required rather than a fixed voltage reference. Consider the SOT-23-8 package size constraints against available board space. Evaluate the need for a manual reset input feature for system testing or recovery. Verify that the operating supply voltage range aligns with the target system's power rails.

Supervisors Part Context

This part belongs to the MAX6753 family of supervisory circuits designed for reliable system management. It complements other variants like MAX6753KA31 which may have different fixed thresholds. The series is widely used in applications requiring robust power monitoring and automated reset mechanisms without complex external components.

Supervisors Replacement Considerations

Direct substitutes include MAX6753KA31+T and MAX6753KA16+T, provided the reset threshold voltage requirements are met. Verify pinout compatibility before substitution. Ensure the replacement part supports the same output configuration and watchdog functionality.
