MAX40203AUK+T

Ultra-Tiny Nanopower, 1A Ideal Diodes  with Ultra-Low-Voltage Drop

二极管 - 通用，功率，开关 Low Current Ideal Diode

General Description MAX40203AUK+T

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 230mV 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.
