Overvoltage Protection Switch/Limiter

Controllers Operate Up to 72V

General Description

Features

The MAX6397/MAX6398 are small, high-voltage overvolt-

age protection circuits. These devices disconnect the

output load or limit the output voltage during an input

overvoltage condition. These devices are ideal for appli-

cations that must survive high-voltage transients such as

those found in automotive and industrial applications.

♦ 5.5V to 72V Wide Supply Voltage Range

♦ 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

When the input voltage exceeds the overvoltage thresh-

old, 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.

Sources Up to 100mA (MAX6397)

♦ Fully Specified from -40°C to +125°C (T )

♦ Small, Thermally Enhanced 3mm x 3mm TDFN

Package

Ordering Information

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.

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.

*Replace “-T” with “+T” for lead-free 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 MAX6397/MAX6398 include internal thermal-shut-

down 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.
