MAX6385XS29D1-T

Supervisors Overview

The MAX6385XS29D1-T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power-supply voltages ranging from 1.8V to 5.0V with a factory-set reset threshold of 2.93V. The device features an active-high, push-pull output and includes a manual reset input. It operates within a supply voltage range up to 5.5V and consumes only 7µA of quiescent current. The reset timeout period is specified at 2.24 seconds minimum. The component is housed in a compact SC-70-4 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage supervision for single power rails with factory-set thresholds.
• Features an active-high push-pull output for direct logic interface compatibility.
• Includes a manual reset input pin for external system control capabilities.
• Designed for ultra-low power consumption suitable for battery-operated applications.

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered portable electronics
• Industrial control systems requiring voltage supervision
• Consumer devices with strict power constraints

Supervisors Procurement Notes

Verify the specific suffix D1-T against official Analog Devices documentation to confirm the exact threshold voltage and packaging configuration. Confirm RoHS compliance status through the manufacturer's latest datasheet. Check availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure the SC-70-4 footprint matches your PCB design requirements before procurement.

Supervisors Selection Notes

Select this component when a single-channel reset circuit with an active-high output is required. The 2.93V threshold suits applications monitoring 3.3V or similar logic levels. Consider the 2.24s timeout if long power-up delays are acceptable. Verify that the manual reset feature aligns with system safety requirements. Compare against other MAX6385 variants if different thresholds or output polarities are needed.

Supervisors Part Context

This part belongs to the MAX6385 series of low-voltage, low-power microprocessor reset circuits. The series offers various threshold voltages and timeout periods to accommodate diverse system designs. The MAX6385 variant specifically provides an active-high output, distinguishing it from active-low counterparts in the same family. It shares the SC-70-4 package and low-power characteristics with related models like the MAX6381 and MAX6387.

Supervisors Replacement Considerations

Direct substitutes include other MAX6385XS29 variants with identical electrical specifications but different packaging options such as µDFN. Cross-reference with MAX6385XS29D1+ for leaded versions if applicable. Ensure any replacement maintains the active-high output polarity and 2.93V threshold accuracy.
