MAX6414UK22+T

Supervisors Overview

The MAX6414UK22+T is a single-channel, ultra-low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage supply and provides an active-low reset output when the monitored voltage falls below a fixed threshold of 2.188V. The device operates within a supply voltage range up to 5.5V and features a typical quiescent current of 7µA. It includes a manual reset input for system control and supports operation across an extended temperature range from -40°C to +125°C. The component is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Ultra-low power consumption with typical 7µA operating current
• Integrated manual reset function for direct user control
• Active-low push-pull reset output for reliable signal driving
• Extended industrial temperature rating for harsh environments

Supervisors Applications

• Battery-powered portable electronic devices requiring low standby current
• Microprocessor systems needing reliable power-fail detection
• Embedded controllers requiring manual reset capability
• Industrial equipment operating in extreme temperature conditions

Supervisors Procurement Notes

Verify the specific suffix 'UK22' corresponds to the 2.188V threshold variant during procurement. Confirm RoHS compliance status as indicated by the '+' suffix. Ensure the SOT-23-5 package matches your PCB footprint requirements. Check manufacturer documentation for any recent lifecycle changes or obsolescence notices prior to finalizing orders.

Supervisors Selection Notes

Select this component when a fixed low-voltage threshold near 2.2V is required for battery monitoring. Consider the manual reset feature if hardware push-button integration is necessary. Evaluate the 7µA quiescent current against system power budgets. Compare against adjustable threshold variants if precise voltage calibration is needed instead of fixed levels.

Supervisors Part Context

This part belongs to the MAX6414 family of single-supply supervisors designed for nanowatt and microwatt applications. It complements other Maxim Integrated supervisory circuits offering watchdog timers or dual-voltage monitoring. The UK series typically denotes specific threshold voltages and package configurations within the broader product line.
