E-Fuse MX6288T Low Loss Power Distribution Switch For USB Bus / Self-Powered Hubs
The MX6288T is a cost effective, single P-MOSFET load switch with ultra-low RDS(ON), optimized for self-powered and bus powered Universal Serial Bus applications.
Input voltage from 2.5V to 5.5V, making it ideal for both 3.3V and 5V systems. A built-in P-channel MOSFET with true shutdown function to eliminate any reversed current flow across the switch. When output voltage is higher than input voltage, power switch is turned off.
The MX6288T offers a programmable current limit threshold between 200mAto 2.4A via an external resistor.

Over Stress Caution
Stresses beyond those listed in Absolute Maximum Ratings may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may affect reliability. Functional operation of the device at any conditions beyond those indicated in the Recommended Operating Conditions section is not implied.
This integrated circuit can be damaged by ESD if you don’t pay attention to ESD protection. The MAXIN MICRO recommends that all integrated circuits be handled with appropriate precautions. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product performance may not be indicated by the electrical characteristics if operated under different conditions.
1. eFuse is latched off until the EN/Fault pin is pulled low and then released or a power on reset is applied to the device.
2. Does not include fan out of EN/Fault function.
3. Pulse test: Pulse width 300 s, duty cycle 2%.
4. Verified by design.
