MAX6855UK22D2+T

Supervisors Overview

The MAX6855UK22D2+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5 V and features a factory-trimmed reset threshold voltage of 2.188 V with an overvoltage threshold of 2.243 V. The device provides an active low, push-pull reset output with a manual reset input capability. It does not include a watchdog timer or battery backup switch. The typical operating supply current is 7 µA. The component is housed in a SOT-23-5 surface-mount package and supports operation across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring with manual reset functionality in a compact five-pin SOT-23 package
• Features ultra-low quiescent current consumption for extended battery life applications
• Provides factory-trimmed reset thresholds ensuring precise voltage supervision without external components

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered portable electronics
• Embedded system reset management

Supervisors Procurement Notes

Verify availability status as this component may be subject to limited supply or obsolescence. Confirm RoHS compliance and lead-free specifications through official manufacturer documentation. Check for alternative part numbers within the MAX685x series if this specific variant is discontinued. Ensure ordering suffixes match required threshold voltages and package types. Consult authorized distributors for current stock levels and lead times.

Supervisors Selection Notes

Select this device when a single-channel supervisor with manual reset is required. Choose based on the specific 2.188 V threshold requirement. Consider the SOT-23-5 package for space-constrained designs. Verify that the absence of a watchdog timer meets system requirements. Compare against other MAX685x variants for different threshold options.

Supervisors Part Context

Part of the MAX6854/MAX6855/MAX6856/MAX6858/MAX6860–MAX6869 family of nanopower microprocessor supervisory circuits. These devices combine voltage monitoring, watchdog timer, and manual reset functions. The family offers ultra-low current consumption and various factory-trimmed reset thresholds. They are designed for applications requiring reliable power management in small packages.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX685x series with compatible threshold voltages. Verify package compatibility and electrical characteristics. Consider MAX6854, MAX6856, MAX6858, or MAX6860 variants if pinout and function align. Confirm availability of newer revisions or equivalent parts from Analog Devices.
