MAX6316LUK45CY-T

Supervisors Overview

The MAX6316LUK45CY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies in digital systems and features a fixed reset threshold voltage of 4.5V. The device operates within a supply voltage range up to 5.5V and draws a typical quiescent current of 10uA. It provides an active-low, push-pull reset output with a minimum power-on reset timeout period of 200ms. The circuit includes a manual reset input and a watchdog timer for enhanced system reliability. It is housed in a compact SOT-23-5 surface-mount package and supports operation across an industrial temperature range from -40°C to +125°C.

Supervisors Procurement Notes

Verify the exact suffix CY against official manufacturer documentation to confirm specific package and temperature grade variations. Confirm RoHS compliance status through the latest datasheet as manufacturing processes may evolve. Check for obsolescence or lifecycle changes directly with Analog Devices or authorized distributors before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.5V threshold is required for single-supervision applications. Ensure the design accommodates the SOT-23-5 footprint and the specified operating temperature range. Verify that the active-low push-pull output stage aligns with the target microprocessor reset pin requirements.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. These devices are designed to monitor power supplies and ensure reliable system resets. The family offers various combinations of reset outputs, watchdog timers, and manual reset inputs across multiple threshold voltages.

Supervisors Replacement Considerations

Other members of the MAX6316–MAX6322 family may serve as functional substitutes if their reset thresholds and output configurations match the design requirements. Verify pin compatibility and electrical specifications before substitution.
