200mA/250mA/300mA Current-Limit Switches  
8–MAX794  
General Description  
Features  
♦ Guaranteed Current Limit: 200mA, 250mA, 300mA  
♦ Thermal-Shutdown Protection  
♦ Reverse Current Protection  
♦ 0.2Ω On-Resistance  
♦ 14ms Guaranteed Blanking Time  
♦ FLAG Function (MAX4789/MAX4791/MAX4793)  
♦ 80µA Supply Current  
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 avail-  
able with guaranteed 200mA, 250mA, and 300mA cur-  
rent 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. If after this blanking  
time the load current is greater than the current limit,  
the MAX4789, MAX4791, and MAX4793 enter a latch-  
off state where the switch is turned off and FLAG is  
issued to the microprocessor. The switch can be turned  
on again by cycling the power or the ON pin.  
♦ 8µA Latch-Off Current  
(MAX4789/MAX4791/MAX4793)  
♦ 0.01µA Shutdown Current  
♦ 2.3V to 5.5V Supply Range  
♦ Undervoltage Lockout  
♦ Fast Current-Limit Response Time (5µs)  
♦ TDFN and SOT23/SOT143 Packages  
The MAX4790, MAX4792, and MAX4794 have an  
autoretry feature where the switch turns off after the  
blanking time and then continuously checks to see if  
the overload condition is present. The switch remains  
on after the overload condition disappears.
