MAX6340UK28+

Overview

The MAX6340UK28+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply input with a fixed threshold voltage of 2.8V. The device features an active-low, open-drain reset output and provides a reset delay time of 4.375 ms. It operates in a surface-mount SOT-23-5 package.

Feature Summary

• Monitors a single power supply input for voltage supervision
• Provides an active-low, open-drain reset signal output
• Includes a fixed internal reset timeout delay period

Applications

• Microprocessor system reset circuits
• Portable electronic devices requiring low supply current
• Battery-powered equipment monitoring

Procurement Notes

Verify the specific suffix designation carefully during procurement. The provided model lacks the standard tape-and-reel suffix typically found on this component series. Confirm availability status directly with authorized distributors, as stock levels may be limited or subject to factory special order constraints.

Selection Notes

Select this component when a fixed 2.8V threshold is required for a single-supply application. Ensure the design accommodates the open-drain output configuration, which requires an external pull-up resistor. Verify that the 4.375ms reset delay meets the target system's timing requirements.

Part Context

This part belongs to the MAX6340 family of CMOS microprocessor supervisory circuits designed for portable applications. These devices are characterized by low supply current consumption and small package sizes, making them suitable for space-constrained designs where efficient power management is critical.

Replacement Considerations

Consult official documentation for confirmed substitute part numbers within the same product family before implementation.
