heavy charging currents. This is important in systems with long USB cables where significant voltage drops can occur while fast-charging portable devices. The TP2549 47-m power switch has two selectable, programmable current limits that support port power management by providing a lower current limit that can be used when adjacent ports are experiencing heavy loads. This is important in systems with multiple ports and an upstream supply unable to provide full current to all ports simultaneously. The DCP_Auto scheme detects and selects the proper D+ and D settings to communicate with the attached device, so that it can fast-charge at full current. The integrated CDP detection enables to 1.5-A fast charging of most portable devices with simultaneous data communication. The unique client-mode feature allows software updates to client devices, but avoids power conflicts by turning off the internal power switch while keeping the data line connection. Additionally, the TPS2549 device integrates short-toVBUS protection for D+ and D to prevent damage when D+ and/or D unexpectedly short to VBUS. To save space in the application, the TPS2549 device also integrates ESD protection to pass IEC61000-4-2 without external circuitry on D+ and D. Device Information(1)

When EN is low, the device is disabled, the signal and power switches are OFF. Active-low open-drain output, asserted during overtemperature, overcurrent, and DP_IN and DM_IN overvoltage conditions. See Table 1. Ground connection; should be connected externally to the thermal pad. Connect external resistor to ground to set the high current-limit threshold. Connect external resistor to ground to set the low current-limit threshold and the loaddetection current threshold. Input supply voltage; connect F or greater ceramic capacitor from IN to GND as close to the IC as possible. Power-switch output Active-low open-drain output, asserted when the load exceeds the load-detection threshold Thermal pad on bottom of package. The thermal pad is internally connected to GND and is used to heat-sink the device to the circuit board. Connect the thermal pad to the GND plane. Logic-level control inputs for controlling the charging mode and the signal switches; (see Table 2). These pins tie directly IN or GND without a pullup or pulldown resistor. DESCRIPTION Provide sink current proportional to output current. For cable compensation, connect to the feedback divider of the up-stream voltage regulator.
