ADM6319B31ARJZ-RL7

Supervisors Overview

The ADM6319B31ARJZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold voltage of 3.062 V with an accuracy of 2.5%. The device provides a push-pull active-low reset output and includes a manual reset input. It incorporates a typical reset delay time of 280 ms and consumes 20 µA of quiescent current. The component is housed in a 5-lead SOT-23 package and is specified for operation over an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable system reset generation based on monitored supply voltage levels
• Includes a manual reset input for external control of the reset state
• Delivers a push-pull active-low reset output signal
• Ensures low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Portable electronic devices requiring low standby current
• Industrial control systems operating in harsh environments
• Communication equipment power management circuits

Supervisors Procurement Notes

Verify the specific suffix ARJZ corresponds to the required tape and reel packaging configuration for automated assembly processes. Confirm that the B31 designation matches the exact 3.062 V threshold requirement for your design. Ensure compatibility with the SOT-23-5 footprint during PCB layout finalization. Check for any regional distribution restrictions or lead time variations before placing orders.

Supervisors Selection Notes

Select this component when a fixed 3.062 V threshold is required without adjustable options. Choose the push-pull output variant if driving capacitive loads or requiring strong drive capability compared to open-drain alternatives. Consider the 20 µA quiescent current for efficiency-critical designs. Verify that the 280 ms reset delay meets the timing requirements of the downstream logic components.

Supervisors Part Context

This part belongs to the ADM6319 series of supervisory circuits, which are characterized by high accuracy and low power consumption. The series offers various threshold voltages and output configurations to suit different application needs. The ADM6319 family is widely used in consumer electronics and industrial applications where reliable power monitoring is essential for system stability.

Supervisors Replacement Considerations

Direct substitutes include other ADM6319 variants with identical pinouts but different threshold voltages, such as ADM6319B25ARJZ-RL7 or ADM6319B45ARJZ-RL7, provided the reset threshold can be adjusted in the design. Cross-reference with ADM6322 series parts if open-drain outputs are acceptable instead of push-pull.
