MAX4842 - Overvoltage Protection Controllers

Download the MAX4842 datasheet PDF. This datasheet also covers the MAX4838 variant, as both devices belong to the same overvoltage protection controllers family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX4838

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

MAX4842 turn off the low-cost external n-channel FET(s) to prevent damage to the protected component

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.

19-3044; Rev 1; 4/04 MAX4838–MAX4842 Overvoltage Protection Controllers with Status FLAG 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. The MAX4838/MAX4839 have a 7.4V overvoltage threshold, and the MAX4840/MAX4841 have a 5.8V overvoltage threshold. The MAX4842 has a 4.7V overvoltage threshold. The MAX4838–MAX4841 have an undervoltage lockout (UVLO) threshold of 3.25V while the MAX4842 has a UVLO of 3.0V.
