ADM709MANZ

Supervisors Overview

The ADM709MANZ is a power supply monitor integrated circuit manufactured by Analog Devices Inc., designed to generate system reset signals during power-up, power-down, and brownout conditions. It features a precision voltage threshold of 4.4V suitable for +5V supply monitoring. The device operates with a minimum supply voltage of 1V and includes a minimum power-on reset pulse duration of 140ms. It utilizes an active-low push-pull output driver and is housed in an 8-SOIC package. The component supports a wide operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Generates system reset signals during power-up, power-down, and brownout events
• Features a fixed 4.4V precision voltage threshold for +5V supply monitoring
• Maintains operational functionality with supply voltages as low as 1V
• Provides an active-low push-pull output driver for direct microprocessor interface

Supervisors Applications

• Microprocessor systems requiring critical power supervision
• Computers and controllers needing brownout protection
• Intelligent instruments demanding reliable reset generation
• Automotive systems with strict power monitoring requirements

Supervisors Procurement Notes

Verify the specific suffix MANZ against official Analog Devices documentation to confirm the exact threshold voltage and package variant, as suffixes define electrical and mechanical specifications. Check current lifecycle status, as this part may be subject to end-of-life notices or limited availability. Ensure compatibility with existing PCB footprints and thermal management requirements before procurement.

Supervisors Selection Notes

Select the ADM709MANZ when a fixed 4.4V threshold is required for +5V logic systems. Consider the 140ms minimum reset delay and 1V minimum operating voltage for low-power applications. Compare against MAX709 equivalents if pin-compatible alternatives are needed. Verify that the SOIC-8 package fits the design constraints and that the active-low output matches the target processor's reset input polarity.

Supervisors Part Context

The ADM709 series serves as a cost-effective upgrade to the Maxim Integrated MAX709 family, offering similar functionality within Analog Devices' portfolio. It belongs to the class of simple reset generators and power-supply monitors. The MANZ suffix typically denotes a specific commercial or industrial grade variant within the broader ADM709 lineup, distinguished by its fixed threshold and packaging.

Supervisors Replacement Considerations

Public confirmed substitutes include MAX709MCSA+ and MAX709MESA+. Verify pin compatibility and threshold voltage alignment before substitution.
