MAXIM MAX14984 handbook
Update: 30 September, 2023
The MAX14984 is an integrated VGA port protector and dual USB power switches that detects the insertion and removal of a monitor and automatically connects the graphics controller when a monitor is detected. In addition to normal VGA signals, it also provides up to 55mA to the VGA port via a switched 5V output. The MAX14984 also features a single active-low enable input to control two 5V USB switches. 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 level to a level that is compatible with the logic level of the graphics controller.
