ADM6315-29D4ART-RL

Supervisors Overview

The ADM6315-29D4ART-RL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides an open-drain reset output. The device features a threshold voltage of 2.9V, a manual reset input, and a reset delay time of 28 ms. It operates within a supply voltage range up to 5.5 V and is housed in a 4-lead SOT-143 surface-mount package.

Supervisors Feature Summary

• Provides active-low reset signal via open-drain output when monitored voltage falls below threshold
• Includes manual reset input for system initialization control
• Ensures valid reset output down to low supply voltages

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the specific suffix ART-RL against the manufacturer's current datasheet revision to confirm tape-and-reel packaging and exact threshold tolerance. Confirm RoHS compliance status and lead-free specifications with the supplier prior to ordering, as manufacturing updates may affect material declarations.

Supervisors Selection Notes

Select this component when a simple, low-power supervisor with manual reset capability is required. Ensure the 2.9V threshold aligns with the target rail voltage. Verify that the open-drain output interface matches the receiving logic gate requirements without additional pull-up components if not already present in the design.

Supervisors Part Context

This part belongs to the ADM6315 family of supervisory circuits from Analog Devices. The family offers various threshold options and timeout delays in compact packages. The ADM6315 specifically focuses on basic voltage monitoring with manual reset functionality, distinguishing it from watchdog-enabled variants like the ADM6316 series.

Supervisors FAQ

What is the function of the MR pin?

The MR (Manual Reset) pin allows external assertion of the reset signal, enabling system initialization or recovery independent of the supply voltage level.

Is there a watchdog timer in this device?

No, the ADM6315 does not include a watchdog timer; it functions solely as a voltage supervisor with a fixed reset delay.
