MAX6855UK27D5+T

Supervisors Overview

The MAX6855UK27D5+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 fixed threshold voltage of 2.7 V for monitoring input lines. The device provides an active low, push-pull reset output with a manual reset input capability. It includes a typical reset delay time of 450 ms and consumes a maximum operating supply current of 7 uA. The component is housed in a compact SOT-23-5 surface-mount package and is rated for operation across an extended temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates voltage monitoring with manual reset functionality in a five-pin SOT-23 package
• Provides active low push-pull reset signal assertion upon undervoltage detection
• Operates with ultra-low quiescent current consumption suitable for battery-powered systems

Supervisors Applications

• Microprocessor power supply supervision
• Battery-operated electronic devices requiring voltage monitoring
• Portable equipment power management systems

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing lot details prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to maintain device reliability during assembly processes.

Supervisors Selection Notes

Select this component when a fixed 2.7 V threshold is required for single-supervision applications. Consider the active low output polarity and manual reset pin availability against system logic requirements. Evaluate the 7 uA supply current against total system power budgets for portable designs.

Supervisors Part Context

This part belongs to the MAX6854/MAX6855/MAX6856/MAX6858/MAX6860–MAX6869 family of ultra-low-current microprocessor supervisory circuits. These devices combine voltage monitoring, watchdog timer, and manual reset functions. The MAX6855 variant specifically offers an active low push-pull output configuration.

Supervisors Replacement Considerations

Cross-reference with other MAX6855 variants featuring different threshold voltages if voltage levels differ. Verify compatibility with MAX6854 or MAX6856 series parts regarding output polarity and reset timing characteristics before substitution.
