ADM6316AY29ARJZ-R7

Supervisors Overview

The ADM6316AY29ARJZ-R7 is a single-channel power supply management circuit manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 5-lead SOT-23 package (MO-178AA). The device features a fixed reset threshold voltage of 2.9V, with a typical accuracy of 2.5%. It includes a manual reset input and supports push-pull active-low output stages. The component consumes low power, typically drawing 5 µA, and guarantees valid reset output down to VCC = 1V. It is RoHS compliant and lead-free.

Supervisors Feature Summary

• Integrates watchdog timer functionality with multiple timeout options for system reliability
• Includes a dedicated manual reset input pin for external control
• Provides glitch immunity against power supply transients
• Maintains valid reset output signals at low supply voltages

Supervisors Applications

• Microprocessor systems requiring supervision
• Controller circuits needing automatic reset capabilities
• Portable equipment utilizing battery backup switching

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 confirms RoHS compliance and lead-free status as indicated in official documentation. Confirm the reset threshold voltage matches the required 2.9V specification for the target application. Ensure the 5-lead SOT-23 package footprint aligns with the PCB design constraints. Check for any specific handling requirements associated with the reel packaging format.

Supervisors Selection Notes

Select this component when a fixed 2.9V threshold is required for supervising a single power rail. The inclusion of a watchdog timer and manual reset input makes it suitable for complex digital systems. Consider the low quiescent current for battery-operated designs. Verify that the push-pull output stage meets the drive requirements of the downstream logic or microcontroller reset pin.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common features such as watchdog timers, manual reset inputs, and low power consumption. The primary differentiation among family members lies in the reset threshold voltage options and output stage configurations, allowing designers to tailor the supervision characteristics to specific voltage rails.

Supervisors Replacement Considerations

Direct substitutes within the same family include parts with identical 2.9V thresholds and compatible packages, such as ADM6316AY29ARJZ-RL7. Cross-family replacements require matching the reset threshold, output type, and package dimensions. Verify that alternative components support the same industrial temperature range and watchdog functionality if these features are critical to the design.
