MAX6356LSUT+T

Overview

The MAX6356LSUT+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three voltage inputs with thresholds of 2.93V, 4.63V, and an adjustable level. The device features active-low push-pull reset outputs referenced to VCC1 and operates within a supply range up to 5.5V. It provides a minimum power-on reset pulse width of 100ms and includes a debounced manual reset input. The component is housed in a SOT-23-6 package and supports surface mount installation across a temperature range of -40°C to +85°C.

Feature Summary

• Monitors multiple power-supply voltages including preset and adjustable thresholds
• Provides active-low push-pull reset outputs referenced to VCC1
• Includes a debounced TTL/CMOS-compatible manual-reset input

Applications

• System reliability improvement in embedded electronics
• Monitoring dual or triple voltage rails in portable devices
• Ensuring accurate reset sequencing for microprocessors

Procurement Notes

Verify the specific suffix LSUT against the official Maxim Integrated part numbering system to confirm threshold levels and package type. Confirm RoHS compliance status and REACH registration details directly from the manufacturer's current documentation. Ensure the ordering information matches the required voltage thresholds and output configuration for the target application design.

Selection Notes

Select this component when monitoring three distinct voltage sources is required within a compact SOT-23-6 footprint. The adjustable threshold option allows flexibility for non-standard voltage rails. Verify that the 100ms minimum reset timeout meets the system startup requirements. Consider the push-pull output drive capability if interfacing directly with logic inputs without external pull-ups.

Part Context

This device belongs to the MAX6351–MAX6360 series of microprocessor supervisors designed to replace discrete components. The series improves system accuracy by integrating multiple monitoring functions into a single IC. These devices assert all reset outputs if any monitored supply drops below its threshold, ensuring comprehensive protection for sensitive digital circuits.

Replacement Considerations

Consult the MAX6351–MAX6360 family datasheet for pin-compatible alternatives with different voltage thresholds or output configurations. Verify functional equivalence regarding reset timing and manual reset behavior before substitution.
