Maxim Integrated MAX14984
The MAX14984 is a complete VGA port protector with dual USB power switches. The device features all the circuitry required to detect the insertion and removal of a monitor and automatically connect the graphics controller when a monitor is detected. The MAX14984 features a single active-low enable input to control two 5V USB switches.| Part No. | MAX14984 |

GENERAL DESCRIPTION
A switched 5V output provides up to 55mA to the VGA port in addition to normal VGA signals. Each switch supplies 500mA of current with less than 250mV drop from VCC, and is protected against short-circuit faults. Two active-low fault outputs indicate when a fault condition is detected on either output. High-bandwidth analog switches exceed VESA rise/fall time requirements for the RGB channels. The horizontal and vertical synchronization (H/V) buffers shift logic levels to support +2.5V to +5.0V CMOS or TTL-compatible graphics controllers while meeting the VESA drive capability requirement of Q8mA. An internal 2.5V regulator and pullup resistors on the monitor side translate the DDC voltage levels to be compatible with low-voltage graphics controllers. The MAX14984 features high-ESD protection of Q8kV Human Body Model (HBM) on all VGA and USB outputs. The device is available in a 24-pin (4mm x 4mm) TQFN package and is specified over the -40NC to +85NC extended temperature range.
