MAX16997AAUA+T

Supervisors Overview

The MAX16997AAUA+T is a high-voltage watchdog timer manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an input voltage range of up to 40 V and features a fixed threshold voltage of 1.255 V. The device provides an open-drain output with a reset delay time of 116.09 ms. It supports manual reset functionality and includes a battery backup switch option. The component is housed in an UMAX-8 surface-mount package and functions as a voltage supervisory circuit.

Supervisors Feature Summary

• High-voltage monitoring capability for systems requiring supervision up to 40 V
• Integrated watchdog timer with adjustable timeout functionality
• Open-drain output configuration for flexible interface compatibility

Supervisors Applications

• Industrial control system power supervision
• Automotive electronic module monitoring
• High-voltage embedded system reset management

Supervisors Procurement Notes

Verify current availability status directly with authorized distributors, as supply may be limited or subject to factory special order constraints. Confirm RoHS compliance details and specific packaging options such as reel or cut tape requirements prior to ordering. Ensure the UMAX-8 package footprint matches your PCB design specifications.

Supervisors Selection Notes

Select this component when a high-voltage input range up to 40 V is required for voltage supervision. The fixed 1.255 V threshold and 116.09 ms reset delay are key parameters for timing-sensitive applications. Consider the UMAX-8 package size for space-constrained designs requiring surface-mount installation.

Supervisors Part Context

This part belongs to the MAX16997 series of high-voltage watchdog timers from Analog Devices / Maxim Integrated. It is categorized under PMIC - Power Management ICs, specifically within the Supervisory Circuits subcategory. The device is designed for robust voltage monitoring in demanding environments.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the MAX16997 family, such as the MAX16998AAUA/V+, which shares similar high-voltage watchdog characteristics and UMAX-8 packaging.
