MAX6398ATT+T Description

Short technical summary and product information.

The MAX6398ATT+T is a high-voltage overvoltage protection circuit designed by Maxim Integrated. It monitors input or output voltages and controls an external n-channel MOSFET to isolate or limit the load during overvoltage transients. This device is suitable for applications requiring survival of high-voltage transients, such as industrial environments.

 

The MAX6398ATT+T operates over a wide supply voltage range of 5.5V to 72V. It offers an adjustable overvoltage threshold, allowing users to set protection levels. The integrated charge pump ensures full enhancement of the external MOSFET for low RDS(ON) performance. The device can either disconnect the load or act as a voltage limiter during overvoltage conditions.

 

For applications where a linear regulator is also needed, the MAX6397 variant provides an always-on, low-current regulator capable of sourcing up to 100mA. Both MAX6397 and MAX6398 include internal thermal-shutdown protection. They are specified for operation from -40°C to +125°C and are available in small, thermally enhanced 3mm x 3mm TDFN packages.

 

Key features include a wide 5.5V to 72V supply voltage range, user-adjustable overvoltage threshold, and thermal-shutdown protection. The device is ideal for industrial applications, notebook computers, and wall cube power devices.
