MAX16997AAUA+

Supervisors Overview

The MAX16997AAUA+ is a high-voltage watchdog timer manufactured by Analog Devices Inc./Maxim Integrated. It operates within an input voltage range of up to 40 V and features a threshold voltage of 1.255 V. The device provides one monitored input with an open-drain output type and includes a built-in watchdog timer function. It does not support manual reset or battery backup switching. The reset delay time is specified at 116.09 ms. Designed for surface-mount installation, it is housed in a UMAX-8 package. The component supports operation across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• High-voltage monitoring capability supporting inputs up to 40 V
• Integrated watchdog timer functionality for system reliability
• Open-drain output configuration for flexible interfacing

Supervisors Applications

• Voltage supervisory circuits requiring high-voltage tolerance
• System monitoring in automotive or industrial environments
• Watchdog timer implementations in embedded systems

Supervisors Procurement Notes

Verify current availability status directly with authorized distributors or the manufacturer, as supply constraints may apply. Confirm RoHS compliance details and specific packaging options such as reel or cut tape if required for production. Ensure the UMAX-8 package footprint matches your PCB design guidelines before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with high-voltage tolerance is required. The fixed 1.255 V threshold and 116.09 ms reset delay define its timing characteristics. Consider the open-drain output and lack of manual reset features against system requirements. Verify that the operating temperature range meets environmental conditions.
