MAX6351TZUT

Overview

The MAX6351TZUT+T is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within an extended temperature range of -40°C to +85°C and utilizes a surface-mount SOT-23-6 package. The device provides two active-low, push-pull reset outputs referenced to VCC1 and VCC2 respectively. Key electrical parameters include a minimum power-on reset pulse width of 100ms and a supply current of 20µA. Voltage thresholds are factory-set at 2.93V and 4.63V.

Feature Summary

• Dual voltage monitoring with independent reset outputs for VCC1 and VCC2
• Active-low push-pull reset outputs ensure compatibility with standard logic families
• Debounced manual reset input compatible with TTL and CMOS standards

Applications

• Multi-rail embedded system power supervision
• Microprocessor reset generation in industrial control units
• Portable equipment power management requiring low quiescent current

Procurement Notes

Verify the specific suffix 'TZUT' against the manufacturer's official part numbering guide to confirm exact threshold voltages and package type. Confirm RoHS compliance status and check for any product change notices or end-of-life announcements prior to finalizing procurement plans.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required. Ensure the fixed threshold levels align with the target supply voltages. Verify that the SOT-23-6 footprint matches the PCB layout constraints and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors designed to improve system reliability. These devices replace discrete components by integrating multiple reset functions into a single IC. The series offers various threshold options and package configurations to suit diverse design needs.

Replacement Considerations

Consult the official datasheet for cross-reference information. Potential substitutes may include other parts from the MAX635x family with matching channel counts and output types.
