ADM6319C46ARJZ-RL7

Supervisors Overview

The ADM6319C46ARJZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply integrity in electronic systems. It operates within a supply voltage range of up to 5.5 V and features a fixed overvoltage threshold of 4.699 V. The device provides a push-pull reset output with a standard delay time of 280 ms. It supports manual reset functionality via an integrated input pin. The component consumes a typical operating current of 20 uA and is available in a surface-mount SOT-23-5 package. It is rated for industrial temperature operation from -40 C to +85 C.

Supervisors Feature Summary

• Integrated manual reset input for system control
• Push-pull active-low reset output stage
• Low quiescent current consumption for power efficiency
• Guaranteed reset validity down to low supply voltages

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered equipment voltage supervision
• Industrial control system reset management
• Portable electronics power integrity verification

Supervisors Procurement Notes

Verify the specific suffix RL7 indicates reel packaging configuration when sourcing. Confirm the C46 designation matches the required 4.699 V threshold for your application design. Check RoHS compliance status through official manufacturer documentation prior to integration. Ensure the SOT-23-5 footprint aligns with your PCB layout requirements. Validate availability status as distribution channels may report limited stock or discontinuation notices.

Supervisors Selection Notes

Select this component when a fixed high-voltage threshold near 4.7 V is required for system protection. The 280 ms reset delay suits applications tolerant of moderate startup times. Consider the 20 uA standby current suitable for battery-operated devices requiring minimal drain. The manual reset feature allows external intervention during fault conditions. Verify compatibility with the target logic levels and ensure the industrial temperature range meets environmental specifications.

Supervisors Part Context

This part belongs to the ADM6319 series of supervisory circuits from Analog Devices. The series offers various threshold options ranging from 2.5 V to 5 V. Other variants in the family differ primarily in reset thresholds and timeout configurations. The ADM6319C46ARJZ-RL7 specifically targets applications needing precise overvoltage detection with manual reset capability in a compact surface-mount package.

Supervisors Replacement Considerations

Direct substitutes include other ADM6319 variants with different threshold voltages if the 4.699 V limit is not critical. Cross-reference with ADM6316, ADM6317, ADM6318, ADM6320, ADM6321, and ADM6322 series parts for similar functional blocks. Verify pinout compatibility and output drive strength before substitution. Ensure thermal and electrical ratings match the original design constraints.
