MAX6315US46D2-T

Supervisors Overview

The MAX6315US46D2-T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply input with a fixed threshold voltage of 4.63V and an overvoltage threshold of 4.70V. The device features an active-low, open-drain reset output and includes a manual reset input. It operates within a supply voltage range up to 5.5V and supports a reset timeout period of 200ms. The component is housed in a surface-mount SOT-143-4 package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset when monitored supply voltage falls below the preset threshold or upon manual assertion.
• Features an open-drain output compatible with various logic families for flexible interface connections.
• Integrates a debounced manual reset input to allow user-initiated system resets without external components.

Supervisors Applications

• Microprocessor and digital system power supply monitoring
• Battery-powered equipment requiring low quiescent current supervision
• Portable electronics utilizing single-supply architectures

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free packaging specifications against the latest datasheet revision. Check for obsolescence notices as this series may be subject to discontinuation. Ensure proper handling procedures for ESD-sensitive surface-mount devices during assembly.

Supervisors Selection Notes

Select this part when a fixed 4.63V threshold is required for standard logic systems. Consider the open-drain output configuration for level-shifting applications. Verify that the 200ms timeout meets system startup requirements. Compare against MAX6314 if bidirectional I/O compatibility is necessary instead of open-drain output.

Supervisors Part Context

This component belongs to the MAX6315 family of uP reset circuits designed for low-power applications. It shares the SOT-143-4 footprint with other variants in the series but differs in threshold voltage and output type compared to the MAX6314. The device eliminates external timing components by integrating internal hysteresis and timeout circuits.
