Frequently Asked Questions

Up to what input voltage can the MAX6398ATT+ protect a circuit?

The MAX6398ATT+ operates and provides overvoltage protection for systems with input voltages up to 72 V, making it suitable for industrial motor drives, telecom equipment, and high-voltage power supply designs that need robust 1-channel fault protection.

What package does the MAX6398ATT+ use and how compact is it?

The MAX6398ATT+ is housed in a 6-LFCSP (Small Outline No-lead) package measuring 3x3x0.75 mm, offering a very small footprint of just 9 mm² board area, which helps save space in densely packed power management PCB layouts.

Can the overvoltage threshold of the MAX6398ATT+ be adjusted for different power rails?

Yes, the MAX6398ATT+ features an adjustable threshold, allowing designers to set the trip point to match specific power rail voltages. This flexibility supports a wide range of applications from 5 V logic rails to 72 V industrial supply buses within a single 1-channel IC.

When would a designer choose the MAX6398ATT+ over a fixed-threshold supervisor for overvoltage protection?

Designers choose the MAX6398ATT+ when they need a flexible, adjustable overvoltage trip point rather than a fixed-voltage supervisor, especially for systems operating beyond 12 V or up to 72 V where standard supervisors do not apply. The 1-channel, 6-pin LFCSP solution minimizes external component count.
