MAX6315US26D3-T

Supervisors Overview

The MAX6315US26D3-T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single power supply with a fixed threshold voltage of 2.63V and provides an active-low, open-drain reset output. The device features manual reset functionality and operates within a supply voltage range up to 5.5V. It consumes only 5µA of supply current and offers a typical reset delay time of 140ms minimum. The component is housed in a compact SOT-143-4 surface-mount package and supports 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 factory-set threshold
• Features manual reset input for external control of the reset state
• Utilizes ultra-low quiescent current suitable for battery-powered applications
• Includes active-low open-drain output compatible with various logic families

Supervisors Applications

• Portable electronic devices requiring low standby current
• Microprocessor and digital systems monitoring
• Battery-operated equipment with strict power constraints
• Industrial control systems operating in extreme temperatures

Supervisors Procurement Notes

Verify the exact suffix designation as datasheets often list MAX6315US26D3+T or similar variants. Confirm lead-free status and RoHS compliance through official manufacturer documentation before procurement. Ensure the specific revision matches design requirements for threshold accuracy and timing parameters.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for single-supply monitoring. Consider the SOT-143-4 package for space-constrained designs. Verify that the open-drain output configuration aligns with the target microcontroller's reset input requirements. Check if manual reset capability is necessary for the specific application logic.

Supervisors Part Context

This part belongs to the MAX6315 series of uPower Reset Circuits designed for monitoring power supplies in microprocessor systems. The series emphasizes low power consumption and small footprint, making it ideal for portable electronics. It complements other Maxim Integrated supervisory circuits offering various thresholds and package options.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6315 family with different threshold voltages. Verify functional equivalence with other single-channel open-drain reset supervisors from Analog Devices or third-party manufacturers ensuring matching electrical characteristics.
