2 Description

The TPS254900AQ1EVM-003 enables full evaluation of the TPS254900A-Q1 device. Refer to the schematic in Figure 1. An automotive voltage range input is applied at the J1 connector. The input voltage is regulated by the LMR14030SDDAR buck regulator (U1) and associated circuitry. This provides a nominal 5-V, 3-A output at +5 VDCfor the TPS254900A-Q1 (U2).

The TPS254900A-Q1 internal power switch connects +5 VDCfurnished by the LMR14030SDDAR regulator to VBUS at the downstream facing USB connector, J5. When the internal power switch is ON, the D6 LED (green) illuminates. USB 2.0 data can be passed through the TPS254900AQ1EVM-003 from J5 to J4 when the TPS254900A-Q1 is configured for either SDP or CDP mode using the J6 header. The TPS254900A-Q1 status and fault conditions can be detected using the D3 (blue) and D2 (red) LEDs, respectively.

The TPS254900A-Q1 provides system-level ESD protection in accordance with IEC 61000-4-2 up to ±8kV contact and ±15-kV air discharge at the DP_IN and DM_IN signals going to J5. These pins as well as VBUS pin will also provide detection of shorts to the battery by triggering the FAULT logic and illuminating D2.

The TPS254900A-Q1 provides USB cable voltage droop compensation at the load through the use of the CS pin. Sinking current into the CS pin mirrors the current through the TPS254900A-Q1 power switch at a rate of 82 µA/A. The CS pin current is summed with the LMR14030SDDAR regulator feedback current through R1 causing the voltage at +5 VDCto change with USB downstream load current. The +5 V increases linearly as load current increases. This compensation will keep the load end voltage close to 5 VDC. The default compensation resistor values (R1 and R4) target a USB cable resistance of 200 mΩ. Refer to the TPS254900A-Q1 data sheet for more information.

The TPS254900A-Q1 provides a current detection function through the use of the IMON pin. Connect a resistor between IMON and GND. The system can detect the load current in real time by monitoring the IMON voltage.

EVM Assembly Drawings and Layout Guidelines

5.2 Layout Guidelines

Use the following layout guidelines:

• TPS254900A-Q1 placement: Place the TPS254900A-Q1 near the USB output connector and OUT pin filter capacitors. Connect the exposed pad to the GND pin and the system ground plane using an array of vias.

• IN pin bypass capacitance: Place the 0.1-μF bypass capacitor near the IN pin and make the connection using a low inductance trace.

• DP-OUT, DM-OUT and DP-IN, DM-IN traces: Route these traces as controlled impedance differential pairs per the USB-2.0 specification. Minimize the use of vias in the high-speed data lines. Figure 7 provides a good signal routing example for the high-speed data traces. In this example, the data pairs are routed as edge-coupled microstrips with nominal differential impedance of 90 Ω. The reference plane is tied to GND and is shown in Figure 6. Ensure that the reference plane is void of cuts or splits above the differential pairs to prevent impedance discontinuities.

• ILIM_LO and ILIM_HI pin connections: Current-limit, set-point accuracy can be compromised by stray current leakage from a higher voltage source to the ILIM_LO or ILIM_HI pins. Ensure that there is adequate spacing between IN pin copper/trace and ILIM_LO pin trace to prevent contaminant buildup during the PCB assembly process.

• The capacitor on BIAS helps improve IEC ESD performance, a 2.2-µF capacitor should be placed close to BIAS and the whole “current” path from BIAS to GND across this capacitor should be as short as possible. Do not use a via along the connection traces.

• A 10-µF output capacitor should be placed close to the OUT pin and TVS.

5.3 EMI Containment

EMI containment methods are shown in the following list:

• Use compact loops for dv/dt and di/dt circuit paths (power loops and gate drives)

• Use minimal, yet thermally adequate, copper areas for heat sinking of components tied to switching nodes (minimize exposed radiating surface).

• Use copper ground planes (possible stitching) and top-layer copper floods (surround circuitry with ground floods)

• Use a 4-layer PCB, if economically feasible (for better grounding)

• Minimize the amount of copper area associated with input traces (to minimize radiated pickup)

• Maintain physical separation between input-related circuitry and power circuitry (use ferrite beads as boundary line)

• Possible use of common-mode inductors

Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. Le présent émetteur radio a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne énumérés dans le manuel d’usage et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement interdits pour l'exploitation de l'émetteur
