ADM6316CY46ARJ-RL7

Supervisors Overview

The ADM6316CY46ARJ-RL7 is a supervisory circuit designed for microprocessor-based systems, manufactured by Analog Devices Inc. It monitors power supply voltage levels and provides reset signals with a fixed threshold of 4.6V. The device features a manual reset input and an open-drain active-low output stage. It operates within an industrial temperature range of -40°C to +85°C and consumes low power. The component is housed in a 5-lead SOT-23 package.

Supervisors Feature Summary

• Integrated watchdog timer for code execution integrity monitoring
• Manual reset input for external push-button assertion
• Open-drain active-low reset output stage
• Power supply glitch immunity

Supervisors Applications

• Microprocessor systems
• Controllers
• Intelligent instruments
• Portable equipment

Supervisors Procurement Notes

Verify the specific suffix CY46 confirms the 4.6V threshold and open-drain output configuration against the official datasheet. Confirm RoHS compliance status as manufacturing revisions may vary between leaded and lead-free versions. Ensure the RL7 reel packaging matches inventory requirements. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Supervisors Selection Notes

Select this component when a fixed 4.6V reset threshold is required for system supervision. The open-drain output allows for flexible logic level interfacing. Consider the manual reset feature if external user intervention is needed. Verify that the industrial temperature range meets environmental specifications. Compare against other ADM631x variants if different timeout or output configurations are necessary.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices monitor voltage levels and provide reset signals. Variants differ in reset thresholds, watchdog timeouts, and output stages. The ADM6316 series specifically includes manual reset inputs and various output configurations in a compact 5-lead SOT-23 package.

Supervisors Replacement Considerations

Direct substitutes include other ADM6316 variants with identical pinouts but different thresholds or outputs, such as ADM6316CX41ARJZ-R7 (4.1V) or ADM6316BZ32ARJZ-R7 (3.2V). Ensure functional compatibility regarding output type and timeout settings before substitution.
