ADM709MAR

Supervisors Overview

The ADM709MAR is a single-channel voltage supervisor IC manufactured by Analog Devices Inc., designed for simple reset and power-on reset applications. It features an active-low, push-pull output driver housed in an 8-SOIC surface-mount package with a width of 3.90mm. The device monitors a single voltage input with a threshold of 4.4V. It operates within a supply voltage range of 1V to 5.5V and supports a minimum reset timeout of 140ms, with a maximum active reset time of 380ms. The component functions reliably across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides active-low reset signaling via a push-pull output driver for reliable logic interfacing.
• Monitors a single power rail with a fixed threshold to detect under-voltage conditions.
• Ensures system stability through guaranteed minimum reset timeout durations during power transitions.

Supervisors Applications

• Microprocessor and microcontroller power supply monitoring
• Battery-powered equipment voltage supervision
• Portable instrumentation power management

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm exact electrical parameters and package dimensions. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure the selected variant matches the required operating temperature range and reset timing specifications for the target application environment.

Supervisors Selection Notes

Select this component when a fixed threshold voltage monitor is required for standard digital logic systems. Consider the 8-SOIC package for surface-mount assembly constraints. Evaluate the 4.4V threshold against the specific nominal supply voltage of the circuit to ensure proper reset generation without nuisance tripping during normal operation.

Supervisors Part Context

This part belongs to the ADM709 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and package options to suit different power supply architectures.
