MAX6381LT26D2+

Supervisors Overview

The MAX6381LT26D2+ is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power-supply voltages within the +1.8V to +5.0V range while consuming only 3µA of supply current at +1.8V. The device features a factory-set reset threshold voltage of 2.63V and provides an active-low, push-pull reset output. It operates with a minimum reset timeout period of 560ms after the supply voltage rises above the threshold. The component supports a maximum supply voltage of 5.5V and functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power-supply voltages from +1.8V to +5.0V with ultra-low quiescent current consumption
• Provides a push-pull active-low reset output that asserts when VCC falls below the set threshold
• Maintains reset assertion for a minimum timeout period after VCC exceeds the threshold
• Operates reliably across an extended industrial temperature range

Supervisors Applications

• Microprocessor system power supervision
• Battery-powered portable electronics monitoring
• Industrial control system voltage tracking
• Consumer appliance power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level guidelines to maintain package integrity. Validate that the ordering suffix matches the required pinout and electrical specifications for your design implementation.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is appropriate for the target rail. Consider the 560ms timeout duration against system startup requirements. Evaluate the UDFN-6 package dimensions against available board space. Compare the 3µA current draw against total system power budgets to ensure efficiency targets are met during standby modes.

Supervisors Part Context

This part belongs to the MAX6381-LT series of low-voltage, low-power microprocessor reset circuits. The series offers various threshold voltages and timeout delays to accommodate different system architectures. The LT variant typically denotes specific temperature and accuracy grades compared to other series members like the XR or XS versions.

Supervisors Replacement Considerations

Direct substitutes include other MAX6381 variants with identical pinouts but different thresholds, such as MAX6381LT26D1+T or MAX6381LT26D3+T. Cross-series replacements require verifying compatible output types and package footprints.
