MAX6737XKYHD3+T

Supervisors Overview

The MAX6737XKYHD3+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8 V to 5 V and features a threshold voltage adjustable from 900 mV to 3.3 V. The device monitors two input channels and provides an active-low, push-pull output. It includes manual reset functionality with a fixed reset delay time of 225 ms. The component does not incorporate a watchdog timer or battery backup switch. It is housed in a compact SC-70-5 surface-mount package and supports operation across standard industrial temperature ranges.

Supervisors Feature Summary

• Dual-input voltage supervision with adjustable threshold capabilities
• Active-low push-pull output interface for direct logic integration
• Manual reset control with defined delay timing

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the exact suffix KYHD3 against official manufacturer documentation to confirm pinout and electrical specifications. Confirm availability status as distribution channels may list this part as discontinued or limited stock. Ensure compatibility with existing PCB footprint and thermal requirements before procurement.

Supervisors Selection Notes

Select this component when dual-channel voltage monitoring with adjustable thresholds is required. The SC-70-5 package suits space-constrained designs. Verify that the 225 ms reset delay meets system startup timing requirements. Confirm that the absence of a watchdog timer aligns with the application's fault detection strategy.

Supervisors Part Context

This part belongs to the MAX6737 series of low-power supervisory circuits. The series offers various configurations for single, dual, and triple voltage monitoring. The specific model utilizes the SC-70-5 package, distinguishing it from SOT-23 variants in the same family. It targets applications requiring precise voltage tracking with minimal quiescent current consumption.

Supervisors Replacement Considerations

Consult official cross-reference data for verified substitutes. Generic equivalents may differ in threshold accuracy or package dimensions.
