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 )

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.

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.
