MAX6843UKD0+

Supervisors Overview

The MAX6843UKD0+T is a voltage detector manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 1.8 V and features an adjustable threshold voltage between 900 mV and 1.5 V. The device provides an active low, push-pull output with a reset delay time of 210 ms. It consumes 8.1 uA of operating current and maintains an accuracy of 2.5%. The component functions in a temperature range from -40 C to +85 C and is housed in an SOT-23-5 package.

Supervisors Feature Summary

• Provides manual reset functionality for system supervision
• Features an active low push-pull output driver
• Supports adjustable overvoltage threshold detection

Supervisors Applications

• Ultra-low-voltage power monitoring
• Battery-powered system supervision
• Portable electronic device protection

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as the provided model lacks the standard tape-and-reel indicator. Confirm availability status directly with the manufacturer or authorized distributors, as this specific part number may be subject to limited supply or discontinuation. Ensure the ordering code matches the required packaging format before finalizing procurement.

Supervisors Selection Notes

Select this component when an adjustable threshold and push-pull output are required for ultra-low-voltage applications. Compare it against the MAX6845 variant if an open-drain output is preferred instead. Verify that the 210 ms reset delay meets the system timing requirements and that the 8.1 uA quiescent current fits the power budget constraints.

Supervisors Part Context

This part belongs to the MAX6843 series of ultra-low-voltage P-reset circuits and voltage detectors. It is designed for applications requiring precise monitoring of low supply rails. The series typically includes variants with different output types and fixed thresholds, offering flexibility for various embedded system supervision needs.

Supervisors Replacement Considerations

The MAX6845UKD0+T is a functional alternative within the same family, differing primarily in its open-drain output configuration compared to the push-pull output of the MAX6843.
