MAX6381XR26D3-T

Supervisors Overview

The MAX6381XR26D3-T is a single-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and features a factory-set reset threshold voltage of 2.6V. The device provides an active-low, push-pull reset output with a fixed timeout period of 280ms. It consumes only 7µA of supply current at 1.8V and is available in a compact SC-70-3 surface-mount package. The component supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power-supply voltages and asserts a reset signal when the input falls below the factory-set threshold.
• Provides a guaranteed valid reset output state down to a supply voltage of 1V.
• Features low-power consumption suitable for battery-operated applications.

Supervisors Applications

• Microprocessor system supervision
• Portable electronic devices
• Battery-powered instrumentation

Supervisors Procurement Notes

Verify the specific suffix D3-T indicates tape-and-reel packaging configuration. Confirm the lead-free status (+) if required by assembly specifications. Check current availability as distribution channels may list this part as discontinued or limited stock. Ensure the 2.6V threshold matches the target rail voltage requirements.

Supervisors Selection Notes

Select this component when a fixed 2.6V threshold and 280ms delay are required. The SC-70-3 package offers space efficiency for dense PCB layouts. Consider alternative threshold voltages if the monitored rail differs significantly from 2.6V. Verify that the active-low push-pull output interface is compatible with the downstream logic inputs.

Supervisors Part Context
