MAX6315US31D3+T

Supervisors Overview

The MAX6315US31D3+T is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for microprocessor reset applications. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.08 V with an overvoltage threshold of 3.14 V. The device provides an active low, open-drain output with a manual reset capability and a reset delay time of 200 ms. It consumes only 5 uA of operating supply current and maintains an accuracy of 1.8%. The component is housed in a SOT-143-4 package and supports surface mount installation across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides manual reset functionality via an external push-button switch for system control.
• Features an open-drain output configuration suitable for interfacing with various logic families.
• Ensures reliable operation through high accuracy voltage monitoring with minimal power consumption.

Supervisors Applications

• Microprocessor reset circuits requiring manual intervention
• Battery-powered systems needing ultra-low standby current
• Portable electronic devices with strict power constraints

Supervisors Procurement Notes

Verify the exact suffix D3+T against official datasheets to confirm tape-and-reel packaging specifications. Confirm that the manufacturer designation matches Analog Devices or Maxim Integrated as listed in public records. Ensure the RoHS compliance status aligns with current regulatory requirements for your region. Cross-reference the SOT-143-4 package dimensions with standard footprint libraries to prevent assembly errors during PCB design validation.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-input voltage supervision. The open-drain output necessitates an external pull-up resistor; ensure the system design accounts for this requirement. Consider the 200 ms reset delay to guarantee stable power ramp-up before processor initialization. Verify that the manual reset feature integrates correctly with the target application's user interface or safety protocols without causing unintended system resets.

Supervisors Part Context

This part belongs to the MAX6315 series of supervisory circuits, which are optimized for low-power applications. Unlike the MAX6314, which offers bidirectional outputs, the MAX6315 utilizes an open-drain architecture. It differs from the MAX6858 series by including manual reset capabilities and operating at higher maximum supply voltages. The series is distinct from the MAX6845, which targets ultra-low-voltage applications below 1.8 V.
