MAX6398 - Overvoltage Protection Switch/Limiter Controllers

Download the MAX6398 datasheet PDF. This datasheet also covers the MAX6397 variant, as both devices belong to the same overvoltage protection switch/limiter controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX6397/MAX6398 are small, high-voltage overvoltage protection circuits.

These devices disconnect the output load or limit the output voltage during an input overvoltage condition.

Key Features

  • 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 RDS(ON) Performance.
  • 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).

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 automotive and industrial applications. 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 useradjustable overvoltage threshold, the external n-channel MOSFET is turned on by the GATE output.
