MAX6343RUT-T

Overview

The MAX6343RUT-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of +1V to +5.5V and features a fixed reset threshold voltage of 3.08V. The device provides an active-low, open-drain reset output with a typical reset delay time of 200ms. It is housed in a compact SOT-23-6 surface-mount package and supports manual reset functionality via an MR input pin. The component is designed for industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Monitors power supply voltages to ensure system reliability
• Provides active-low reset signal with open-drain output
• Includes manual reset input for controlled system initialization

Applications

• Digital system power supply monitoring
• Microprocessor reset circuits
• Battery-powered equipment supervision

Procurement Notes

Verify the exact suffix 'T' against official datasheets to confirm tape-and-reel packaging specifications. Confirm RoHS compliance status as indicated in current manufacturer documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices before procurement planning.

Selection Notes

Select this component when a fixed 3.08V threshold is required for single-supply monitoring. Ensure the open-drain output configuration matches the downstream logic interface requirements. Verify that the SOT-23-6 package dimensions fit the available PCB real estate constraints.

Part Context

This part belongs to the MAX6342–MAX6345 family of 6-pin µP reset circuits. These devices offer factory-trimmed threshold voltages and integrate power-fail comparators for low-battery detection. The family improves system accuracy compared to discrete solutions.

Replacement Considerations

Cross-reference with MAX6343RUT+T for lead-free variants. Verify functional compatibility with MAX6344RUT-T if a different threshold voltage is acceptable.
