ADM6316AY27ARJZ-R7

Supervisors Overview

The ADM6316AY27ARJZ-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 2.7V, with a guaranteed reset output valid down to VCC = 1V. It includes a manual reset input and supports multiple reset timeout options including 1ms, 20ms, 140ms, and 1120ms minimums. The component is RoHS compliant and lead-free.

Supervisors Feature Summary

• Integrates watchdog timer functionality with manual reset input capability for enhanced system reliability
• Provides configurable reset output stages including push-pull active-low, open-drain active-low, and push-pull active-high configurations
• Ensures power supply glitch immunity and maintains low power consumption during operation

Supervisors Applications

• Microprocessor systems requiring voltage supervision
• Controllers needing reliable power-on reset sequences
• Portable equipment utilizing battery-powered architectures

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 corresponds to the reel packaging format and RoHS compliance status as indicated in official documentation. Confirm the 2.7V threshold designation matches the required application voltage levels. Ensure compatibility with the 5-lead SOT-23 footprint during PCB layout review. Cross-reference the manufacturer's latest datasheet for any updates on environmental compliance or pinout definitions prior to final procurement authorization.

Supervisors Selection Notes

Select this component when a fixed 2.7V threshold is required for supervising a single power rail. The inclusion of a manual reset input allows for external control over the reset state, which is critical for specific boot sequences. Consider the available reset timeout options to match the processor startup time requirements. The industrial temperature range makes it suitable for broader environmental conditions compared to commercial grade parts.

Supervisors Part Context

This part belongs to the ADM6316 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and timeout options to accommodate different microprocessor and controller requirements. The ADM6316 variant specifically integrates watchdog and manual reset features in a compact 5-lead package, distinguishing it from simpler reset generators without these advanced timing controls.

Supervisors Replacement Considerations

Direct replacements within the same family include other ADM6316 variants with different threshold voltages, such as ADM6316AY29ARJZ-R7 (2.9V) or ADM6316CX41ARJZ-R7 (4.1V), provided the threshold voltage matches the design requirement. Ensure the replacement part shares the same package type and electrical characteristics.
