MAX16997AAUA/V+T

Supervisors Overview

The MAX16997AAUA/V+T is a high-voltage watchdog timer manufactured by Analog Devices under the Maxim Integrated brand. It operates within an input voltage range 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 lacks manual reset capability and battery backup switching. The reset delay time is specified at 116.09 ms. Designed for surface mount installation, it is housed in an uMAX-8 package. The component supports an operating temperature range from -40 C to +125 C.

Supervisors Feature Summary

• High-voltage operation capability supporting system inputs up to 40 V
• Integrated watchdog timer functionality for automated fault detection
• Open-drain output configuration for flexible interfacing

Supervisors Applications

• Automotive electronic systems requiring voltage supervision
• Industrial control circuits needing high-voltage monitoring
• Embedded systems utilizing watchdog timer protection

Supervisors Procurement Notes

Verify availability status as current supply may be restricted or limited. Confirm exact ordering suffixes match required packaging options such as reel or cut tape configurations. Ensure compatibility with existing design specifications regarding package type and thermal requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when high-voltage monitoring up to 40 V is required alongside integrated watchdog timing functions. Consider the uMAX-8 package size for space-constrained designs. Verify that the fixed threshold voltage of 1.255 V aligns with system supervision needs. Ensure the open-drain output suits the downstream logic interface requirements.

Supervisors Part Context

This part belongs to the MAX16997 series of supervisory circuits designed for robust voltage monitoring applications. It shares functional similarities with other high-voltage watchdog timers in the Maxim portfolio but offers specific integration of watchdog timing within a compact surface-mount package suitable for automotive and industrial environments.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX16997 family or compatible high-voltage watchdog timers from Analog Devices. Verify pinout compatibility and electrical parameter alignment including threshold voltage and reset delay times before substitution.
