Overvoltage Protection Controller, 1.2 V to 28 V, SOT-23-6

The MAX4866LEUT+T from Maxim Integrated Products is an overvoltage protection controller with reverse polarity protection in a 6 pins SOT-23 package. It protects low voltage systems against high-voltage faults up to +28V and negative voltages down to -28V. The device drives a low-cost complementary MOSFET. If the input voltage exceeds the overvoltage threshold, this device turns off N-channel MOSFET to prevent damage to the protected components. If the input voltage drops below ground, the device turns off the p-channel MOSFET to prevent damage to the protected components. An internal charge pump eliminates the need for external capacitors and drives the MOSFET GATEN for a simple, robust solution. The overvoltage thresholds are preset to +5.8V. When the input voltage drops below the under-voltage lockout threshold, the device enters an 8.5µA low-current standby mode. Also in shutdown (EN set to logic-high), the current is reduced further (0.4µA).

  • Input voltage range from 1.2V to 28V

  • Overvoltage fault FLAG indicator
  • The under-voltage lockout threshold is 2.85V
  • Undervoltage lockout hysteresis is 44mV
  • ±15KV ESD protection is provided to input when bypassed with a 1µF capacitor to ground
  • Overvoltage trip level is 5.80V, overvoltage lockout hysteresis is 55mV
  • Operating temperature range from -40°C to 85°C
  • Cell Phones; Digital Still Cameras; MP3 Players; PDAs and Palmtop Devices
