MAX6841HUKD3+T

Supervisors Overview

The MAX6841HUKD3+T is a microprocessor supervisory circuit designed for ultra-low-voltage systems ranging from +0.9V to +1.5V. It monitors power supplies in digital systems to ensure reliability by eliminating external components. The device features a factory-trimmed reset threshold of 0.788V and includes a debounced manual reset input. It operates within an ambient temperature range of -40°C to +85°C and utilizes a SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors ultra-low-voltage power supplies in microprocessor and digital systems
• Features a factory-trimmed fixed reset threshold voltage
• Includes a debounced manual reset input for user control

Supervisors Applications

• Microprocessor system supervision
• Digital system power monitoring
• Ultra-low-voltage circuit reliability enhancement

Supervisors Procurement Notes

Verify the specific suffix 'H' indicates the correct threshold variant, as the MAX6841 family includes multiple options with different factory-trimmed voltages or adjustable inputs. Confirm the '+T' designation corresponds to the tape-and-reel packaging format required for automated assembly processes. Ensure compatibility with the target operating temperature range of -40°C to +85°C.

Supervisors Selection Notes

Select this component when a fixed, precise reset threshold is required without external adjustment resistors. It is suitable for designs constrained by space due to its compact SOT-23-5 footprint. Consider the active high/low output configuration and push-pull drive capability when interfacing with downstream logic circuits that require strong signal integrity.

Supervisors Part Context

This part belongs to the MAX6841–MAX6845 family of ultra-low-voltage µP reset circuits manufactured by Maxim Integrated, now part of Analog Devices Inc. The family provides cost-effective solutions for system supervision by integrating essential functions into a single small package, reducing bill-of-materials complexity for low-voltage applications.

Supervisors Replacement Considerations

Cross-reference with other MAX684x variants such as MAX6841DUKD3+ for different package types or MAX6843/MAX6844 if an externally adjustable reset threshold is preferred over the fixed factory-trimmed value. Verify pinout compatibility before substitution.
