MAX6351TWUT+T

Overview

The MAX6351TWUT+T is a dual voltage supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an ambient temperature range of -40°C to +85°C and utilizes a surface-mount SOT-23-6 package. The device features two monitored input channels with fixed threshold voltages of 2.93V and 4.63V. It provides a push-pull/totem pole output configuration with an active-low reset signal. The minimum reset timeout duration is specified at 100ms. The component is currently in an active production status.

Feature Summary

• Dual-channel voltage supervision with fixed thresholds for critical power rails
• Active-low reset output utilizing a push-pull or totem pole driver architecture
• Guaranteed minimum reset timeout period ensuring stable system initialization

Applications

• Embedded systems requiring reliable power-up sequencing
• Microprocessor and microcontroller supply monitoring
• Battery-powered devices needing voltage level verification

Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct threshold voltages and package type. Confirm RoHS compliance status and environmental certifications prior to integration. Cross-reference the specific ordering code with authorized distributor catalogs to validate current availability and manufacturing lifecycle status. Ensure storage conditions adhere to moisture sensitivity level requirements.

Selection Notes

Select this component when dual independent voltage rails require simultaneous supervision with fixed activation points. The SOT-23-6 footprint offers space efficiency for compact designs. Verify that the required reset delay meets system timing constraints, as the device specifies a minimum timeout. Consider the push-pull output capability if driving loads without external pull-up resistors is necessary.

Part Context

This part belongs to the MAX6351 series of microprocessor supervisory circuits designed for low-power applications. The series typically includes variants with different threshold combinations and package options. It serves as a support circuit for maintaining system integrity by detecting under-voltage conditions and initiating resets when power levels fall below defined limits.

Replacement Considerations

Consult official substitution guides for compatible dual-supervisor alternatives within the same product family. Verify pinout compatibility and electrical parameter alignment before swapping components.
