ADM6315-31D1ARTRL7

Supervisors Overview

The ADM6315-31D1ARTRL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a maximum supply voltage of 5.5 V and features an open-drain reset output. The device provides a fixed threshold voltage of 3.08 V to detect under-voltage conditions. It includes a manual reset input for system control and offers a typical reset delay time of 140 ms. The component is housed in a compact SOT-143-4 surface-mount package, suitable for space-constrained applications requiring reliable power management supervision.

Supervisors Feature Summary

• Provides open-drain active-low reset signal generation based on monitored supply voltage levels
• Includes dedicated manual reset input pin allowing external assertion of the reset state
• Operates with low quiescent current consumption to minimize power drain during standby modes

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring under-voltage detection
• Industrial control units needing reliable reset sequencing

Supervisors Procurement Notes

Verify the specific suffix ARTRL7 indicates reel packaging configuration when sourcing. Confirm the manufacturer is Analog Devices Inc. or authorized distributor. Check RoHS compliance status against current regulatory requirements. Ensure the part number matches the exact threshold voltage specification required for your design. Validate availability through official channels as distribution status may vary.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-supervision applications. Choose the SOT-143-4 package for compact surface-mount designs. Consider the open-drain output compatibility with downstream logic levels. Verify that the 140 ms reset delay meets the timing requirements of the target microcontroller or processor. Ensure the operating temperature range aligns with the environmental conditions of the final application.

Supervisors Part Context

This part belongs to the ADM6315 series of microprocessor supervisory circuits from Analog Devices. The series offers various threshold voltages and timeout options to suit different power rail requirements. The ADM6315 family is characterized by its small footprint and low power consumption, making it suitable for portable and industrial electronics where space and energy efficiency are critical design constraints.

Supervisors Replacement Considerations

Cross-reference with ADM6315 variants having similar threshold voltages and package types. Verify functional equivalence regarding reset delay and output configuration before substitution.
