ADM708ARMZ

Supervisors Overview

The ADM708ARMZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range of 1 V to 5.5 V and features a typical reset threshold voltage of 4.4 V. The device provides a manual reset input for user-initiated control and includes power-fail detection capabilities. It delivers a fixed reset delay time of 280 ms and supports both active high and active low output configurations. With a maximum supply current of 350 uA, it is suitable for battery-powered applications. The component is housed in an MSOP-8 surface-mount package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrated power-fail detection for monitoring supply voltage anomalies
• Configurable output polarity supporting active high or active low signals
• Manual reset input capability for external system control
• Fixed reset delay timer ensuring stable initialization sequences

Supervisors Applications

• Processor supervisor circuits requiring reliable power monitoring
• Battery-operated electronic devices needing low standby current
• Industrial control systems operating in extended temperature environments
• Portable instrumentation utilizing surface-mount packaging constraints

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics, as variations exist within the family. Confirm RoHS compliance status through the manufacturer's current datasheet. Note that availability may vary by region; consult authorized distributors for current stock status. Ensure the selected package matches the PCB footprint requirements. Validate the reset threshold voltage against the specific application needs before finalizing procurement.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with configurable output logic is required. Consider the 4.4 V threshold if monitoring standard 5 V rails. Evaluate the 280 ms delay against system startup timing requirements. The MSOP-8 package offers space efficiency for dense layouts. Verify that the 350 uA maximum supply current aligns with power budget constraints. Ensure the manual reset feature integrates correctly with the system's control interface.

Supervisors Part Context

The ADM708ARMZ belongs to the ADM708 series of processor supervisors from Analog Devices. This series focuses on providing robust power management solutions for digital systems. The ARMZ suffix indicates a lead-free, halogen-free variant compliant with environmental standards. The series typically includes variants with different thresholds and packages to suit diverse design requirements. These components are widely used in consumer electronics and industrial equipment where power reliability is critical.

Supervisors Replacement Considerations

Check the ADM708SARZ for SOIC-8 package compatibility. Verify the ADM706 series for alternative threshold voltages. Confirm functional equivalence with ADM709 models if watchdog features are needed. Ensure pin-to-pin compatibility before substituting.
