MAX16155ABAD+

Supervisors Overview

The MAX16155ABAD+ is a nanoPower supervisory circuit and watchdog timer manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V with a fixed threshold voltage of 1.5 V. The device features an open-drain output and provides a standard reset timeout of 80 µs, alongside a specific reset delay time of 200 ms. It functions in temperatures from -40°C to +125°C and consumes 400 nA of operating current. Accuracy is specified at 2.5%. The component is housed in a SOT-23-6 surface-mount package.

Supervisors Feature Summary

• Integrates voltage supervision with a built-in watchdog timer for comprehensive system monitoring.
• Features ultra-low power consumption suitable for battery-operated applications.
• Provides manual reset capability via dedicated input pin.
• Delivers reliable reset signals with configurable timeout characteristics.

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing robust power failure detection
• Industrial control units operating in wide temperature ranges

Supervisors Procurement Notes

Verify availability status carefully as the MAX16155ABAD+ may be subject to limited supply or discontinuation. Confirm exact ordering suffixes and packaging types with authorized distributors. Ensure compliance with RoHS directives and check for alternative sources if stock is restricted. Validate lead times prior to finalizing procurement plans due to potential supply chain constraints affecting this specific part number.

Supervisors Selection Notes

Select this component when a combined supervisor and watchdog function is required in a minimal footprint. The fixed 1.5 V threshold suits low-voltage logic systems. Consider the SOT-23-6 package for space-constrained PCB layouts. Verify that the 400 nA quiescent current meets strict power budget requirements. Ensure the 200 ms reset delay aligns with system startup timing needs.

Supervisors Part Context

Part of the nanoPower series designed for energy-efficient monitoring. Belongs to the MAX1615x family of supervisory circuits. Manufactured by Analog Devices Inc./Maxim Integrated. Designed for surface-mount assembly. Provides single-channel voltage monitoring with integrated watchdog functionality.

Supervisors Replacement Considerations

Check for MAX16155ABAD+T variant which shares identical electrical specifications but differs in tape-and-reel packaging. Verify pin compatibility before substituting with other MAX1615x family members. Ensure replacement parts maintain the same 1.5 V threshold and SOT-23-6 form factor.
