MAX708SEUA

Supervisors Overview

The MAX708SEUA+ is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for monitoring single power supply rails. It operates within a supply voltage range of 1.2 V to 5.5 V and features a threshold voltage of 2.93 V with an accuracy of 2.5%. The device provides a reset delay time of 200 ms and supports manual reset functionality. It draws a typical operating supply current of 135 uA and can handle a power dissipation of up to 470.6 mW. The component is housed in an UMAX-8 surface-mount package and functions across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed threshold of 2.93 V and high accuracy for reliable system monitoring.
• Features a push-pull output configuration supporting both active high and active low logic states for flexible integration.
• Includes manual reset capability allowing external control over the reset state independent of voltage levels.

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system voltage supervision
• Portable instrumentation power management

Supervisors Procurement Notes

Verify the specific suffix 'U' indicates the UMAX-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the ordering part number matches the required pinout and thermal characteristics for your PCB layout. Check for any lead-free certification requirements if applicable to your manufacturing standards.

Supervisors Selection Notes

Select this component when a compact surface-mount solution is required for single-rail voltage monitoring. The UMAX-8 package offers a small footprint suitable for space-constrained designs. Consider the 2.93 V threshold and 200 ms delay against your system's startup timing requirements. Evaluate the 135 uA quiescent current impact on overall battery life for portable applications.

Supervisors Part Context

The MAX708 series consists of low-cost, low-power voltage monitoring circuits designed to ensure proper system operation by detecting out-of-specification voltages. The SEUA variant specifically utilizes the UMAX-8 package, distinguishing it from other package options like SOIC-8. These devices are part of Analog Devices' portfolio of power management ICs aimed at providing reliable supervisory functions for digital systems.

Supervisors FAQ

What is the reset delay time for the MAX708SEUA+?

The reset delay time is 200 ms, ensuring that the reset signal remains asserted for a sufficient duration after the supply voltage drops below the threshold.

Does the MAX708SEUA+ include a watchdog timer?

No, the MAX708SEUA+ does not include a built-in watchdog timer; it functions solely as a voltage supervisor with manual reset capability.
