● Thermally Self-Protecting
● -40°C to +125°C Temperature Range
General Description
The MAX40200 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. Typical voltage drop is 43mV at
500mA, with the voltage drop increasing linearly at higher
currents. 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. The MAX40200
operates from a supply voltage of 1.5V to 5.5V.
The MAX40200 is available in a tiny, 0.73mm X 0.73mm,
4-bump wafer-level package (WLP), with a 0.35mm bump
pitch and only 0.5mm high and 5-pin SOT-23 package.
The MAX40200 operates over the extended -40°C to
+125°C temperature range.
