MAX40203
Description
The MAX40203 is an ideal diode current-switch with forward voltage drop that is approximately an order of magnitude smaller than that of Schottky diodes. When forward biased and enabled, the MAX40203 conducts with 90m V of voltage drop while carrying currents as high as 1A. During a short-circuit or a fast power-up, the device limits its output current to 2A. The MAX40203 thermally protects itself and any downstream circuitry from overcurrent conditions.
This ideal diode operates from a supply voltage of 1.2V to 5.5V. The supply current is relatively constant with load current, and is typically 300n A. When disabled (EN = low), the ideal diode blocks voltages up to 6V in either direction, makes it suitable for use in most low-voltage, portable electronic devices.
The MAX40203 is available in a tiny, 0.77mm x 0.77mm, 4-bump WLP, with a 0.35mm bump pitch and a 5-pin SOT-23 package. It is specified over the automotive -40°C to +125°C temperature range.
