MAX6340UK29/V+T

Overview

The MAX6340UK29/V+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It provides reset and watchdog timer functions for digital systems. The device monitors voltage levels and generates a reset signal when the supply voltage drops below a specified threshold. It features a manual reset input and an open-drain reset output. The component operates within a specific voltage range and includes a programmable watchdog timer to prevent software lockups. It is housed in a compact SOT-23 package, suitable for space-constrained applications requiring reliable system supervision.

Feature Summary

• Provides precise voltage monitoring with a fixed trip point
• Includes a watchdog timer to detect software failures
• Features a manual reset input for user-initiated system resets
• Offers an open-drain reset output compatible with various logic families

Applications

• Portable consumer electronics requiring low-power supervision
• Industrial control systems needing watchdog functionality
• Embedded systems with limited board space

Procurement Notes

Verify the exact suffix 'V+T' against official Analog Devices documentation to confirm tape-and-reel packaging and temperature grade. Ensure the part number matches the specific voltage threshold required for your design. Cross-reference with the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications before procurement.

Selection Notes

Select this component when a fixed voltage threshold reset is required alongside watchdog capabilities. Consider the SOT-23 package size for space-sensitive designs. Verify that the operating voltage range of the MAX6340 aligns with your system's power supply rails. Check if the open-drain output interface meets your logic level requirements.

Part Context

The MAX6340 series belongs to Maxim Integrated's family of microprocessor supervisory circuits. These devices are designed to enhance system reliability by monitoring power supplies and preventing erratic behavior due to brown-outs or software crashes. The UK29 variant specifies a particular reset threshold voltage, distinguishing it from other members of the MAX6340 lineup with different trip points.

Replacement Considerations

Check Analog Devices' official replacement guide for direct equivalents. Verify pin-to-pin compatibility and identical electrical characteristics such as reset threshold and watchdog timeout values. Ensure any substitute part supports the same SOT-23 package and operating temperature range.
