The MAX40203ANS+T is an ideal diode current-switch designed for low-voltage, portable electronic devices. It features an ultra-low forward voltage drop, approximately an order of magnitude smaller than Schottky diodes, enabling longer battery life.
When forward biased and enabled, the MAX40203 conducts with a typical voltage drop of 90mV while carrying currents as high as 1A. During a short-circuit or fast power-up, the device limits its output current to 2A and provides thermal protection. It operates from a supply voltage range of 1.2V to 5.5V, with a low supply quiescent current typically around 300nA.
When disabled, the ideal diode blocks voltages up to 6V in either direction. The MAX40203ANS+T is available in a tiny 4-bump WLP package (0.77mm x 0.77mm) with a 0.35mm bump pitch, making it suitable for space-constrained designs. It is specified for an operating temperature range of -40°C to +125°C.
Applications include notebook and tablet computers, battery backup systems, cellular phones, electronic toys, USB-powered peripherals, and portable medical devices.
