MAX6385XS40D7-T

Supervisors Overview

The MAX6385XS40D7-T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8V to 5V and features a fixed reset threshold of 4.0V. The device provides an active-high, push-pull output and includes manual reset functionality. It consumes only 7µA of supply current at 1.8V. 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 monitoring of a single power-supply rail with factory-set threshold accuracy.
• Delivers a robust active-high push-pull reset signal for reliable logic interfacing.
• Integrates manual reset capability allowing external assertion of the reset state.

Supervisors Applications

• Microprocessor system power supervision
• Battery-powered portable electronics
• Industrial control board voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix D7 indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation as lead-free variants exist within the series. Ensure the active-high output polarity matches the target design requirements, as other suffixes may offer active-low options.

Supervisors Selection Notes

Select this part when a fixed 4V threshold is required for systems operating between 1.8V and 5V. The SC-70-4 package is suitable for space-constrained designs. Consider the 7µA quiescent current for battery efficiency. Verify that the active-high output polarity aligns with the downstream controller's input logic requirements.

Supervisors Part Context

This component belongs to the MAX6385XS family of low-voltage, low-power microprocessor reset circuits. The 'XS' designation typically denotes factory-set thresholds with specific output polarities and packages. It complements adjustable variants like the MAX6385LT series, offering simplified integration for standard voltage rails without external resistor networks.

Supervisors Replacement Considerations

Cross-reference with MAX6385XS40D5+T or MAX6385XS40D7+ for potential pin-compatible alternatives with different packaging or compliance statuses. Verify electrical parameters match exactly before substitution.
