MAX6319LHUK26C

Supervisors Overview

The MAX6319LHUK26C+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.6V to 5.5V and features a fixed reset threshold voltage of 2.58V with an accuracy of 1.5%. The device provides a push-pull output that can be configured as active high or active low, offering a minimum reset timeout period of 140ms. It includes a manual reset input and consumes only 3µA of quiescent current. The component is housed in a compact SOT-23-5 package and supports operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a manual reset input for system initialization control alongside automatic power-on reset functionality.
• Provides configurable push-pull reset outputs supporting both active-high and active-low logic states.
• Maintains ultra-low power consumption suitable for battery-operated applications through minimal quiescent current draw.

Supervisors Applications

• Monitoring power supplies in portable digital systems
• Ensuring reliable startup sequences in microprocessor-based designs
• Providing brown-out protection for embedded controllers

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm threshold voltage and output configuration. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary. Ensure the ordering part number matches the required electrical specifications exactly before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.58V threshold is required for low-voltage monitoring. Consider the manual reset feature if external system initialization is necessary. Verify that the SOT-23-5 package fits the design constraints and that the 140ms timeout meets the system's stability requirements during power-up.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices are designed to monitor power supplies and processor activity in digital systems. The family offers various combinations of reset outputs and thresholds, providing flexibility for different voltage monitoring needs in compact form factors.

Supervisors Replacement Considerations

Check for other parts within the MAX6319 series with similar threshold voltages. Verify pin compatibility and electrical characteristics before substituting with generic supervisor ICs. Ensure any replacement maintains the same manual reset capability and output drive strength.
