MAX6315US25D1

Supervisors Overview

The MAX6315US25D1+T is a voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 2.5 V. The device provides an active-low, open-drain reset output with a typical reset delay time of 140 ms. It supports manual reset functionality and consumes a maximum quiescent current of 5 µA. The component is housed in a compact SOT-143-4 package and is rated for operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable system reset generation when monitored supply voltage drops below the specified threshold.
• Features low quiescent current consumption suitable for battery-powered applications.
• Includes manual reset input capability for external control of the reset state.

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Embedded systems needing precise voltage supervision
• Industrial equipment operating in extreme temperature environments

Supervisors Procurement Notes

Verify the specific suffix 'D1' against official manufacturer documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with the target PCB footprint for the SOT-143-4 package. Confirm RoHS compliance status through the latest datasheet or supplier certification documents before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.5 V threshold is required for single-supply monitoring. Consider the open-drain output configuration for interfacing with various logic levels. Evaluate the 140 ms reset delay against system startup requirements. Verify that the manual reset feature aligns with the design's fault recovery strategy.

Supervisors Part Context

This part belongs to the MAX6315 series of simple reset circuits designed for monitoring single power supplies. The series offers various threshold voltages and package options to suit different application needs. The US25 designation indicates the specific 2.5 V threshold version within this family.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the MAX6315 series with matching thresholds. Verify functional equivalence if considering alternative manufacturers' voltage supervisors with similar open-drain outputs and manual reset capabilities.
