The MAX40203AUK+T is an ideal diode current switch from Analog Devices / Maxim Integrated, designed for low-voltage applications. It offers a significantly lower forward voltage drop compared to Schottky diodes, typically 90mV at 1A, which contributes to longer battery life in portable devices.
This ideal diode operates over a wide supply voltage range of 1.2V to 5.5V and can conduct currents up to 1A. During short-circuit or fast power-up events, it limits output current to 2A and provides thermal protection. When disabled, it blocks voltages up to 6V in either direction.
The MAX40203AUK+T is available in a compact SOT-23-5 package, making it suitable for space-constrained designs. It features a low supply quiescent current of typically 300nA and a low reverse leakage current of 10nA. The operating temperature range is -40°C to +125°C.
Key applications include notebook and tablet computers, battery backup systems, cellular phones, and USB-powered peripherals.
