MAX4794 - 200mA/250mA/300mA Current-Limit Switches

Download the MAX4794 datasheet PDF. This datasheet also covers the MAX4789 variant, as both devices belong to the same 200ma/250ma/300ma current-limit switches family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX4789

MAX4794 family of switches feature internal current limiting to prevent damage to host devices due to faulty load conditions.

These analog switches have a low 0.2Ω on-resistance and operate from 2.3V to 5.5V input voltage range.

MAX4789–MAX4794 200mA/250mA/300mA Current-Limit Switches General Description The MAX4789–MAX4794 family of switches feature internal current limiting to prevent damage to host devices due to faulty load conditions. These analog switches have a low 0.2Ω on-resistance and operate from 2.3V to 5.5V input voltage range. They are available with guaranteed 200mA, 250mA, and 300mA current limits, making them ideal for SDIO and other load switching applications. When the switch is on and a load is connected to the port, a guaranteed blanking time of 14ms ensures that the transient voltages settle down.
