MAX6315US31D1-T

Supervisors Overview

The MAX6315US31D1-T is a CMOS 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 fixed threshold voltage of 3.1V for monitoring power supplies. The device provides an active-low, open-drain reset output with a manual reset input capability. It includes a reset delay time of 1.4ms and maintains high accuracy of 1.8%. Designed for surface-mount installation in SOT-143-4 packages, it supports operating temperatures from -40°C to +125°C with a low operating supply current of 5µA.

Supervisors Feature Summary

• Provides reliable supervision of single power supply inputs with precise threshold detection
• Features bidirectional compatibility through open-drain output structure suitable for various logic levels
• Includes manual reset functionality allowing external control over system reset states

Supervisors Applications

• Microprocessor (µP) reset circuits in digital systems
• Power supply monitoring in battery-operated devices
• Embedded controller supervision requiring manual reset capability

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead times as availability may vary. Ensure proper handling procedures are followed due to sensitivity to electrostatic discharge. Cross-reference datasheet specifications against application requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 3.1V threshold is required for power supply monitoring. Consider the open-drain output type if interfacing with varying logic voltages. Evaluate the extended temperature range suitability for harsh environments. Assess the need for manual reset functionality versus fully automatic operation.
