MAX4842 Datasheet Overvoltage Protection Controllers

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-3044; Rev 1; 4/04 MAX4838–MAX4842 Overvoltage Protection Controllers with Status FLAG.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX4838–MAX4842 are overvoltage protection ICs that protect low-voltage systems against voltages of up to 28V.

If the input voltage exceeds the overvoltage trip level, the MAX4838–MAX4842 turn off the low-cost external n-channel FET(s) to prevent damage to the protected components.

An internal charge pump eliminates the need for external capacitors and drives the FET gate for a simple, robust solution.

Key Features

  • include a 15kV ESD-protected input (when bypassed with a 1µF capacitor) and a shutdown pin (EN) to turn off the device (MAX4838/MAX4840/ MAX4842). All devices are offered in a small 6-pin SC70 package and are specified for operation from -40°C to +85°C. Features.
  • Overvoltage Protection Up to 28V.
  • Preset 7.4V, 5.8V, or 4.7V Overvoltage Trip Level.
  • Drive Low-Cost NMOS FET.
  • Internal 50ms Startup Delay.
  • Internal Charge Pump.
  • Undervoltage Lockout.
