ADM709TARZ

Supervisors Overview

The ADM709TARZ is a single-channel voltage supervisor IC manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and monitors input voltages between 4.65 V and 4.75 V. The device features an active-low, push-pull output driver with a maximum reset delay time of 380 ms. Designed for surface-mount installation, it is housed in an 8-pin SOIC package measuring 5 x 4 x 1.5 mm. The component supports an industrial operating temperature range from -40 °C to +85 °C.

Supervisors Feature Summary

• Provides reliable power-supply monitoring with active-low push-pull output drive capability
• Supports surface-mount integration via compact 8-lead SOIC packaging
• Operates across extended industrial temperature ranges for robust environmental performance

Supervisors Applications

• Industrial control system power supervision
• Embedded processor voltage monitoring
• Consumer electronics power management

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm the exact monitored threshold voltage variant matches design requirements, as values may vary within the specified 4.65 V to 4.75 V range. Ensure compatibility with the 8-SOIC footprint during PCB layout finalization.

Supervisors Selection Notes

Select this component for applications requiring simple power-on reset functionality without manual reset inputs or watchdog timers. The low supply current and wide operating voltage range make it suitable for battery-backed or regulated logic circuits. Verify that the 380 ms maximum reset delay aligns with system startup timing constraints.
