MAX6351LTUT

Overview

The MAX6351LTUT+T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent power supplies with fixed thresholds of 3.08V and 4.63V. The device features active-low, open-drain reset outputs referenced to VCC1 and VCC2 respectively. Key electrical parameters include a maximum supply voltage of 5.5V, a reset delay time of 180ms, and an operating supply current of 20µA. It operates within a temperature range of -40°C to +85°C and provides 1.5% accuracy for threshold monitoring.

Feature Summary

• Dual-channel voltage supervision with independent reset outputs referenced to respective supply rails
• Integrated manual reset input with debouncing capability for system control
• Low-power operation suitable for battery-supplied applications

Applications

• Monitoring dual power rails in embedded systems
• Microprocessor power supply supervision
• Industrial control system reset management

Procurement Notes

Verify the exact suffix configuration as the base model MAX6351LTUT may have variations. Confirm RoHS compliance status and check for obsolescence notices from Analog Devices. Ensure the package type matches SOT-23-6 requirements for your PCB layout.

Selection Notes

Select this component when precise monitoring of two distinct voltage levels is required. The fixed thresholds eliminate the need for external resistor dividers. Consider the open-drain output requirement for pull-up resistor implementation in the design phase.

Part Context

Part of the MAX6351-MAX6360 family of multi-voltage supervisors designed to improve system reliability. These devices replace discrete components with integrated solutions offering higher accuracy and lower profile packaging options for space-constrained designs.

Replacement Considerations

Check for MAX6351LTUT+T or other suffix variants within the same series. Verify pin compatibility and threshold voltage matching before substitution.
