MAX6738XKLD3

Supervisors Overview

The MAX6738XKLD3+T is a low-power dual- or triple-voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors up to three voltage inputs and provides reset signals via an open-drain or open-collector output. The device operates within a supply voltage range of up to 5.5 V and features adjustable thresholds, with specific examples including 4.625 V and adjustable settings. It offers high accuracy of 3% and includes manual reset functionality. The component is housed in a compact SC-70-5 package and operates across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors multiple voltage rails simultaneously for system integrity
• Provides configurable reset outputs with open-drain or open-collector topology
• Supports manual reset input for controlled system recovery

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for microprocessor units (MPUs)
• Portable electronic devices requiring low-power oversight

Supervisors Procurement Notes

Verify the exact suffix (e.g., +T) for packaging configuration. Confirm threshold voltage specifications match design requirements as variants exist. Check availability status as some listings indicate obsolete or limited stock conditions. Ensure RoHS compliance documentation is obtained from the manufacturer or authorized distributor before procurement.

Supervisors Selection Notes

Select this component when multi-voltage supervision is required in space-constrained designs. The SC-70-5 package suits applications with strict footprint limitations. Verify that the adjustable threshold capabilities align with the specific voltage rails being monitored. Consider the low quiescent current if battery life is a critical design parameter.

Supervisors Part Context

This part belongs to the MAX673x series of supervisory circuits designed for low-power applications. It complements other Maxim Integrated voltage supervisors by offering dual or triple channel monitoring in a minimal footprint. The series is commonly used in consumer electronics and industrial control systems where reliable power management is essential.

Supervisors Replacement Considerations

Direct substitutes may include other MAX673x series variants with compatible pinouts and electrical characteristics. Verify package compatibility (SC-70-5) and threshold voltage ranges before substitution. Cross-reference with Analog Devices' official replacement guide for confirmed equivalents.
