ADM6315-31D2ARTRL7

Supervisors Overview

The ADM6315-31D2ARTRL7 is a supervisory circuit featuring a fixed 3.08V reset threshold voltage and an integrated manual reset input. It operates within a supply voltage range of 1.2V to 5.5V, providing accurate monitoring for microprocessors and memory systems. The device includes a programmable watchdog timer with a timeout period selectable via external components, ensuring system recovery from software faults. It offers a push-pull active-low output and utilizes an SOT-23-5 package for compact board space.

Supervisors Feature Summary

• Integrated manual reset button input for user-initiated system restarts
• Programmable watchdog timer functionality to detect software malfunctions
• Active-low push-pull reset output signal generation
• Low supply current consumption for power-sensitive applications

Supervisors Applications

• Microprocessor and microcontroller system supervision
• Memory protection circuits requiring brown-out detection
• Embedded systems with watchdog timer requirements
• Portable electronic devices needing low-power monitoring

Supervisors Procurement Notes

Verify the specific suffix D2A against the manufacturer's official datasheet to confirm pinout configuration and electrical characteristics. Ensure the ordering code matches the required temperature grade and packaging format. Cross-reference the part number with authorized distributors to validate authenticity and avoid counterfeit components. Confirm that the selected variant aligns with the intended application's voltage and timing specifications.

Supervisors Selection Notes

Select this component when a fixed reset threshold near 3.1V is required alongside manual reset capability. Consider the ADM6315 series if a built-in watchdog timer is necessary for fault recovery. Evaluate the SOT-23-5 package size constraints against available PCB real estate. Compare alternative thresholds if the system operating voltage differs significantly from the 3.08V trip point.

Supervisors Part Context

This part belongs to the ADM6315 family of supervisory circuits designed for reliable system monitoring. The series provides various reset thresholds and features such as manual resets and watchdog timers. The ADM6315-31D2ARTRL7 specifically denotes the 3.08V threshold version in a reel-trimmed leadless package, suitable for automated surface-mount assembly processes.

Supervisors Replacement Considerations

Direct substitutes include other ADM6315 variants with different reset thresholds or package options. Verify compatibility regarding reset delay times and watchdog timeout configurations before substitution. Ensure replacement parts maintain the same supply voltage range and output drive capabilities.
