Analog Devices / Maxim Integrated MAX40203 Low Current Ideal Diode
Analog Devices MAX40203 Low Current Ideal Diode is an ultra-tiny nano-power device with a forward voltage drop that is less than the Schottky diodes. This diode thermally protects itself and any downstream circuitry from over-current conditions and provides better battery life. The Analog Devices MAX40203 diode limits its output current to 2A during a short circuit or a fast power-up mode. These diodes are ideal for powerline fault recorders, battery backup systems, cellular phones, portable medical devices, notebooks, and tablet computers.Features
