MAX6316LUK29CX+

Supervisors Overview

The MAX6316LUK29CX+ is a voltage supervisory circuit in the MAX6316–MAX6322 family, designed to monitor power supplies and microprocessor activity. It features a fixed reset threshold of 2.93V with an overvoltage threshold of 2.974V. The device operates within a supply voltage range up to 5.5V and includes a manual reset input alongside a watchdog timer. It provides an active-low push-pull output and offers a reset delay time of 200ms. The component maintains high accuracy of 1.5% and consumes only 10µA of operating current. It is housed in a compact SOT-23-5 package and supports an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

Supervisors Procurement Notes

Verify availability status as this part may be subject to limited supply or factory special order conditions. Confirm RoHS compliance details through official documentation before procurement. Ensure the specific suffix matches required electrical parameters. Check for obsolescence notices from Analog Devices. Validate that the SOT-23-5 package aligns with PCB design constraints.

Supervisors Selection Notes

Select this component when a fixed 2.93V threshold is required for single-supply monitoring. The inclusion of both watchdog and manual reset functions makes it suitable for complex digital systems. Consider the 10µA quiescent current for battery-powered designs. Verify that the 200ms reset delay meets system timing requirements. Ensure the operating temperature range covers the intended environment.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. The family offers various combinations of reset outputs and timeout periods. The LUK29 variant specifically denotes the 2.93V threshold version. These devices are characterized for operation from -40°C to +125°C. The family is designed to provide reliable reset signals for microprocessors and memory devices.

Supervisors Replacement Considerations

Other variants within the MAX6316–MAX6322 family may serve as substitutes if different thresholds or output types are acceptable. Verify pinout compatibility with the SOT-23-5 package. Ensure equivalent electrical specifications such as reset delay and current consumption. Consult the manufacturer's selector guide for cross-referencing options.
