MAX16155ABAB+T

Supervisors Overview

The MAX16155ABAB+T is a nanoPower supervisor and watchdog timer manufactured by Analog Devices Inc./Maxim Integrated. It monitors a single voltage channel with a threshold of 1.5V. The device features an active-low reset output with open-drain or open-collector configuration. The standard reset timeout is 80µs. It operates within a temperature range of -40°C to +125°C TA. The component is housed in a surface-mount SOT-23-6 package.

Supervisors Feature Summary

• Integrates power supply monitoring and watchdog timer functions in a single chip
• Provides low-active reset signal with configurable timeout duration
• Supports open-drain or open-collector output interface for flexible system integration

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset management
• Watchdog timer implementation in portable devices

Supervisors Procurement Notes

Verify the exact suffix 'ABAB' against official Maxim Integrated documentation, as standard listings often reference 'ABAD'. Confirm current availability status through authorized distributors, as supply constraints may affect lead times. Ensure the ordering part number matches the specific package and temperature grade requirements for your design.

Supervisors Selection Notes

Select this component when a combined supervisor and watchdog function is required in a minimal footprint. The 1.5V threshold suits low-voltage logic systems. Consider the SOT-23-6 package size for space-constrained designs. Verify that the 80µs default timeout meets the system's recovery timing requirements without external adjustment.

Supervisors Part Context

This part belongs to the nanoPower series, designed for ultra-low power applications. It complements other Maxim Integrated supervisors like the MAX16152-55 family. The device simplifies board design by integrating reset generation and watchdog functionality, reducing component count compared to discrete solutions.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX1615x family. Verify electrical parameter compatibility, especially reset thresholds and timeout values. Ensure the replacement supports the same SOT-23-6 package and operating temperature range.
