EVALUATION KIT AVAILABLE  
MAX6397/MAX6398  
Overvoltage Protection Switch/Limiter  
Controllers Operate Up to 72V  
General Description  
Features  
● 5.5V to 72V Wide Supply Voltage Range  
The MAX6397/MAX6398 are small, high-voltage over-  
voltage protection circuits. These devices disconnect  
the output load or limit the output voltage during an  
input overvoltage condition. These devices are ideal for  
applications that must survive high-voltage transients  
such as those found in industrial applications.  
● Overvoltage Protection Controllers Allow User to Size  
External n-Channel MOSFETs  
● Internal Charge-Pump Circuit Ensures MOSFET  
Gate-to-Source Enhancement for Low R  
Performance  
DS(ON)  
The MAX6397/MAX6398 monitor the input or output  
voltages and control an external n-channel MOSFET to  
isolate or limit the load from overvoltage transient energy.  
When the monitored input voltage is below the user-  
adjustable overvoltage threshold, the external n-channel  
MOSFET is turned on by the GATE output. In this mode,  
the internal charge pump fully enhances the n-channel  
MOSFET with a 10V gate-to-source voltage.  
● Disconnect or Limit Output from Input During  
Overvoltage Conditions  
● Adjustable Overvoltage Threshold  
● Thermal-Shutdown Protection  
● Always-On, Low-Current (37µA) Linear Regulator  
Sources Up to 100mA (MAX6397)  
● Fully Specified from -40°C to +125°C (T )  
J
When the input voltage exceeds the overvoltage threshold,  
the protection can disconnect the load from the input by  
quickly forcing the GATE output low. In some applications,  
disconnecting the output from the load is not desirable. In  
these cases, the protection circuit can be configured to  
act as a voltage limiter where the GATE output sawtooths  
to limit the voltage to the load.  
● Small, Thermally Enhanced 3mm x 3mm TDFN Package

The MAX6397 also offers an always-on linear regulator  
that is capable of delivering up to 100mA of output current.  
This high-voltage linear regulator consumes only 37µA of  
quiescent current.  
*Replace “-T” with “+T” for lead(Pb)-free/RoHS-compliant packages.  
**EP = Exposed pad.  
The MAX6397 linear regulator is offered in four output  
voltage options and a choice of a 92.5% or 87.5% POK  
threshold assertions. See the Selector Guide.  
The regulator is offered with output options of 5V, 3.3V,  
2.5V, or 1.8V. An open-drain, power-good output (POK)  
asserts when the regulator output falls below 92.5% or  
87.5% of its nominal voltage.  
Selector Guide and Typical Operating Circuit appear at end  
of data sheet.  
Pin Configurations  
The MAX6397/MAX6398 include internal thermal-  
shutdown protection, disabling the external MOSFET  
and linear regulator if the chip reaches overtemperature  
conditions. The devices operate over a wide 5.5V to  
72V supply voltage range, are available in small TDFN  
packages, and are fully specified from -40°C to +125°C.
