MAX6315US26D3

Supervisors Overview

The MAX6315US26D3 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single input channel with a threshold voltage of 3.08 V and an overvoltage threshold of 3.14 V. The device features an active low, open-drain output type and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and maintains an accuracy of 1.8%. The component has a reset delay time of 200 ms and consumes 5 uA of operating supply current. It is housed in a SOT-143-4 package and functions reliably between -40 C and +125 C.

Supervisors Feature Summary

• Provides automatic power-supply supervision with factory-set thresholds for reliable system monitoring
• Features an open-drain output compatible with various logic families for flexible interface integration
• Includes manual reset capability allowing external control over the reset state

Supervisors Applications

• Microprocessor (µP) reset circuits
• Battery-powered systems requiring low standby current
• Portable instrumentation

Supervisors Procurement Notes

Verify the specific suffix D3 against the manufacturer's official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the SOT-143-4 package dimensions align with your PCB footprint. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Supervisors Selection Notes

Select this component when a fixed threshold near 3.08 V is required for single-channel monitoring. Consider the open-drain output configuration for compatibility with pull-up resistors. Evaluate the 5 uA supply current against battery life requirements. Verify that the 200 ms timeout meets the system's startup timing constraints.

Supervisors Part Context

This part belongs to the MAX6315 series of simple reset/power-on reset circuits. These devices are designed to monitor power-supply voltages and assert a reset signal when the supply falls below a specified threshold. The series offers various threshold voltages and packages to suit different application needs.

Supervisors Replacement Considerations

Check the MAX6315US26D3+G48 as a potential variant with similar specifications. Verify exact threshold and package compatibility before substitution.
