MAX40200AUK+T

MAX40200AUK+T is an ultra-tiny micropower, 1A ideal diode with ultra-low voltage drop. It is an ideal diode current switch that drops so little voltage that it approaches an order of magnitude better than Schottky diodes. When forward-biased and enabled, the MAX40200 conducts with as little as 85mV of voltage drop while carrying currents as high as 1A. The MAX40200 thermally protects itself, and any downstream circuitry, from overtemperature conditions. When disabled (EN = low) the MAX40200 blocks voltages up to 6V in either direction, making it suitable for most low-voltage, portable electronic devices. Applications include notebook and tablet computers, portable media players, cellular phones, portable/wearable medical devices, electronic toys, USB-powered peripherals.
