MAX4866LELT+T

MAX4866LELT+T is an overvoltage protection controller with reverse polarity protection. It protects low-voltage systems against high-voltage faults up to +28V, and negative voltages down to -28V. It drives a low-cost complementary MOSFET. If the input voltage exceeds the overvoltage threshold, this device turns off the n-channel MOSFET to prevent damage to the protected components. If the input voltage drops below ground, the devices turn 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. In addition, a ±15kV ESD protection is provided to the input when bypassed with a 1µF capacitor to ground. Typical applications are cell phones, digital still cameras, PDAs and palmtop devices, MP3 players.
