MAX6315US26D4-T

Supervisors Overview

The MAX6315US26D4-T is a CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply input with a fixed threshold voltage of 2.6 V and an overvoltage threshold of 2.65 V. The device features an active-low, open-drain reset output and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and maintains accuracy of 1.8%. The component consumes 5 µA of supply current and offers a reset delay time of 140 ms minimum. It is housed in a compact SOT-143-4 surface-mount package and functions reliably across an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage supervision for single-channel power rails with low quiescent current consumption suitable for battery-powered applications.
• Features an active-low open-drain reset output compatible with standard digital logic interfaces without requiring external pull-up resistors.
• Includes a dedicated manual reset input pin allowing system operators to initiate a controlled reset sequence independently of voltage levels.

Supervisors Applications

• Portable electronic devices requiring extended battery life through ultra-low power monitoring
• Embedded systems needing reliable power-on reset sequences under varying thermal conditions
• Industrial control units utilizing single-supply architectures with strict voltage tolerance requirements

Supervisors Procurement Notes

Verify the specific suffix D4 against official datasheets to confirm the 2.6V threshold variant, as the MAX6315 series contains multiple threshold options. Confirm RoHS compliance status and lead-free designation (+) if required by assembly specifications. Check manufacturer lifecycle status as some Maxim Integrated components may be approaching end-of-life phases. Ensure sourcing channels provide authentic parts to avoid counterfeit risks associated with obsolete or high-demand supervisory circuits.

Supervisors Selection Notes

Select this component when a fixed 2.6V threshold is required for single-supply monitoring in space-constrained designs. The SOT-143-4 package offers a small footprint compared to larger alternatives. Consider the 5 µA supply current for energy-sensitive applications. Verify that the open-drain output configuration aligns with the target system's logic level requirements and pull-up capabilities. Ensure the manual reset feature meets system safety protocols.

Supervisors Part Context

This part belongs to the MAX6315 family of uP reset circuits designed for monitoring power supplies in microprocessor and digital systems. The series provides various threshold voltages and packaging options to suit different design constraints. Manufactured by Maxim Integrated, now part of Analog Devices, these circuits eliminate external components typically needed for power management reliability.

Supervisors Replacement Considerations

Consult official cross-reference lists for direct substitutes with identical pinouts and electrical characteristics. Verify that any replacement maintains the 2.6V threshold and SOT-143-4 package compatibility. Ensure functional equivalence regarding reset delay times and manual reset support before integration.
