MAX16998DAUA+T

Supervisors Overview

The MAX16998DAUA+T is a high-voltage watchdog timer manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 40 V and features an adjustable timeout delay for system monitoring. The device provides an open-drain reset output and includes a manual reset input capability. It is housed in an 8-UMAX surface-mount package and is rated for operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• High-voltage tolerance supporting systems up to 40 V
• Adjustable watchdog timeout delay configuration
• Open-drain reset output for flexible interfacing
• Extended industrial temperature rating

Supervisors Applications

• Industrial control system supervision
• Automotive electronics monitoring
• High-voltage power management units

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance documentation matches current regulatory requirements. Validate package integrity upon receipt, as surface-mount components require careful handling. Cross-reference datasheet revisions to ensure functional compatibility with existing designs before procurement finalization.

Supervisors Selection Notes

Select this component when system architecture requires robust supervision for voltages exceeding standard logic levels. The adjustable timeout feature allows customization for specific processor clock speeds. Ensure the open-drain output aligns with the target microcontroller reset pin requirements. Verify that the UMAX-8 package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the MAX16997/MAX16998 series of high-voltage watchdog timers designed for demanding environments. It complements other Maxim Integrated supervisory circuits by offering higher voltage tolerance compared to standard low-voltage counterparts. The series supports critical applications where reliable system reset is essential despite electrical noise or transient conditions.

Supervisors Replacement Considerations

Check for MAX16997AAUA+T if fixed timeout is acceptable. Verify MAX16998DAUA+G for lead-free packaging variations.
