MAX40203 - 1A Ideal Diodes

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 90mV of voltage drop while carrying currents as high as 1A.

Features

  • Lower Voltage Drop in Portable.

MAX40203 Ultra-Tiny nanoPower, 1A Ideal Diodes with Ultra-Low-Voltage Drop General 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 90mV 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 300nA.
