MAX6343TUT+T

Overview

The MAX6343TUT+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). This component provides precise voltage monitoring and reset generation for digital systems. It operates within a supply voltage range of 1.25V to 5.5V, ensuring compatibility with various logic families. The device features a fixed output delay timer to allow power supplies to stabilize before asserting the reset signal. It includes an open-drain or push-pull reset output configurable via external components. The part is housed in a compact 6-pin SOT-23 package, suitable for space-constrained portable applications.

Feature Summary

• Provides reliable system reset under low-voltage conditions
• Configurable output delay for stable power-up sequences
• Compact surface-mount packaging for dense layouts

Applications

• Portable electronic devices requiring brown-out protection
• Microcontroller-based systems needing power-on reset
• Battery-operated equipment with low-voltage cutoff requirements

Procurement Notes

Verify the exact suffix 'TUT+T' against official distributor catalogs to confirm tape-and-reel packaging and lead-free status. Ensure the ordering code matches the specific pinout and electrical characteristics listed in the current datasheet revision. Cross-reference manufacturer part numbers to avoid confusion with similar variants lacking the plus sign or having different thermal grades.

Selection Notes

Select this component when a fixed threshold voltage and programmable delay are required without external resistors. Consider the operating voltage range relative to the system's minimum supply level. Evaluate the package size constraints against available board space. Confirm that the reset output type meets the interface requirements of the connected microprocessor or FPGA.

Part Context

This part belongs to the MAX634x family of supervisory circuits designed for general-purpose reset generation. These devices are engineered to monitor power rails and assert reset signals during abnormal conditions. The family offers various thresholds and delay options to suit different application needs while maintaining high accuracy and low quiescent current consumption.

Replacement Considerations

Check for direct replacements such as other MAX634x variants with compatible voltage thresholds. Verify pin-to-pin compatibility if substituting with parts from other manufacturers. Ensure the replacement supports the same operating temperature range and package style to maintain mechanical fit.
