MAX6315US25D1+T

Supervisors Overview

The MAX6315US25D1+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 2.5 V with an accuracy of 1.8%. The device provides an active-low, open-drain reset output and includes a manual reset input. It offers a typical reset delay time of 140 ms and consumes only 5 µA of operating supply current. 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

• Ultra-low quiescent current consumption for battery-powered applications
• Integrated manual reset input for system control flexibility
• Open-drain output compatible with various logic families
• Compact four-pin SOT-143 surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Microprocessor and digital system power monitoring
• Battery-operated instrumentation and sensors
• Embedded systems with strict space constraints

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm the exact threshold voltage and tolerance specifications. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Check for obsolescence notices or lifecycle changes directly from Analog Devices, as distribution availability may vary by region.

Supervisors Selection Notes

Select this component when a fixed 2.5 V supervision threshold is required for single-input monitoring. Ensure the open-drain output configuration aligns with the target system's pull-up requirements. Verify that the 140 ms reset delay meets the timing constraints of the monitored processor or logic circuit during power-up sequences.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits, which are optimized for low-power operation. The series typically includes variants with different threshold voltages and reset delays. The US45 and US30 designations indicate other threshold options within the same package family, maintaining consistent electrical characteristics and pinout compatibility.

Supervisors Replacement Considerations

Cross-reference with MAX6315US29D1+T or MAX6315US30D1+T if the threshold voltage requirement differs. Verify pinout compatibility before substituting with other Maxim Integrated supervisor ICs.
