MAX6315US26D4+T

Supervisors Overview

The MAX6315US26D4+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single power supply input with a fixed threshold voltage of 2.6 V and an overvoltage threshold of 2.68 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 is housed in a compact SOT-143-4 surface-mount package and functions reliably across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset generation for microprocessors and digital logic circuits upon detection of power supply anomalies.
• Features ultra-low quiescent current consumption suitable for battery-powered applications requiring minimal standby drain.
• Includes a dedicated manual reset input pin allowing external control over the reset state independent of voltage monitoring.

Supervisors Applications

• Monitoring power rails in portable electronic devices
• Ensuring system stability in embedded microprocessor systems
• Providing reset signals for digital logic circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as availability may be limited due to lifecycle status. Confirm RoHS compliance and lead-free specifications match project requirements. Check for obsolescence notices or end-of-life announcements from Analog Devices before finalizing procurement plans to ensure long-term supply chain stability.

Supervisors Selection Notes

Select this part when a fixed 2.6 V threshold is required for single-supervision applications. Ensure the design accommodates the open-drain output configuration requiring an external pull-up resistor. Verify that the SOT-143-4 package fits the PCB layout constraints and that the operating temperature range meets environmental conditions.

Supervisors Part Context

This component belongs to the MAX6315 series of uP reset circuits designed for low-power monitoring. It shares functional similarities with other parts in the family but differs in threshold voltage and package options. The MAX6315 series is widely used in consumer electronics and industrial controls where reliable power supervision is critical for system integrity.

Supervisors Replacement Considerations

Consider MAX6315US26D3+T as a potential alternative if compatible packaging and electrical characteristics are confirmed. Verify pinout compatibility and threshold voltage tolerance before substitution. Consult official datasheets for both components to ensure functional equivalence in the specific application context.
