Key Features

  • Overvoltage protection controller supporting input voltages up to 72 V for high-voltage system protection
  • Adjustable overvoltage threshold enables customization to suit diverse power-rail protection requirements
  • Single-channel architecture in a compact 6-LFCSP 3x3x0.75 mm package minimizes PCB footprint
  • Introduced in 2005 with a YTEOL of 10 years, providing long product lifecycle assurance

Applications

The MAX6398ATT+ is designed for overvoltage protection in industrial power supplies, motor drives, and telecom equipment operating on rails up to 72 V. Its adjustable threshold makes it ideal for protecting sensitive downstream circuits in battery management systems, automotive power modules, and server power conditioning units where transient overvoltage events must be clamped quickly.

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.
