产品概述

The MAX4840AEXT+T is an overvoltage-protection controller with status FLAG in 6 pin SC-70 package. It is an overvoltage protection IC that protect low-voltage systems against voltages of up to +28V. If the input voltage exceeds the overvoltage trip level, the device turn off the low-cost external n-channel FET 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 MAX4840A has a 5.8V overvoltage threshold and undervoltage-lockout threshold of 3.25V. In addition to the single FET configuration, the devices can be configured with back-to-back external FETs to prevent currents from being back-driven into the adapter. On power-up, the device waits for 50ms before driving GATE high. Fault indication output is held low for an additional 50ms after GATE goes high before deasserting. It has an open-drain Fault indication output, it asserts immediately to an overvoltage fault.
  • Supply voltage range is 1.2V to 28V
  • Operating temperature range from -40°C to 85°C
  • ±15KV ESD protected input
  • Shutdown pin to turn off the device
  • Supply current is 80µA
