TI always recommends consulting the latest standard to ensure the most recent and accurate information. Rechargeable portable equipment requires an external power source to charge its batteries. USB ports are convenient locations for charging because of an available 5-V power source. Universally accepted standards are required to ensure host and client-side devices meet the power management requirements. Traditionally, USB host ports following the USB 2.0 Specification must provide at least 500 mA to downstream client-side devices. Because multiple USB devices can be attached to a single USB port through a bus-powered hub, it is the responsibility of the client-side device to negotiate the power allotment from the host to ensure the total current draw does not exceed 500 mA. In general, each USB device can subsequently request more current which is granted in steps of 100 mA, up 500 mA total. The host may grant or deny the request based on the available current. Additionally, the success of the USB technology makes the micro-USB connector a popular choice for wall adapter cables. This allows a portable device to charge from both a wall adapter and USB port with only one connector. One common difficulty has resulted from this. As USB charging has gained popularity, the 500-mA minimum defined by the USB 2.0 Specification or 900 mA defined in the USB 3.0 Specification, has become insufficient for many handsets, tablets and personal media players (PMP) which have a higher rated charging current. Wall adapters and car chargers can provide much more current than 500 mA or 900 mA to fast charge portable devices. Several new standards have been introduced defining protocol handshaking methods that allow host and client devices to acknowledge and draw additional current beyond the 500 mA (defined in the USB 2.0 Specification) or 900 mA (defined in the USB 3.0 Specification) minimum while using a single micro-USB input connector. The devices support four of the most common protocols: • USB Battery Charging Specification, Revision 1.2 (BC1.2) • Chinese Telecommunications Industry Standard YD/T 1591-2009 • Divider mode • 1.2 V on both D+ and D– lines YD/T 1591-2009 is a subset of the BC1.2 specification supported by the vast majority of devices that implement USB charging. Divider and 1.2-V charging schemes are supported in devices from specific yet popular device makers. BC1.2 has three different port types, listed as follows. • Standard downstream port (SDP) • Charging downstream port (CDP) • Dedicated charging port (DCP) The BC1.2 Specification defines a charging port as a downstream facing USB port that provides power for charging portable equipment. Table 2 shows different port operating modes according to the BC1.2 Specification. Table 2. Operating Modes PORT TYPE SUPPORTS USB 2.0 COMMUNICATION MAXIMUM ALLOWABLE CURRENT DRAWN BY PORTABLE EQUIPMENT (A) SDP (USB 2.0) Yes 0.5 SDP (USB 3.0) Yes 0.9 CDP Yes 1.5 DCP No 1.5 Copyright © 2013–2020, Texas Instruments Incorporated Submit Documentation Feedback Product Folder Links: TPS2513 TPS2513A TPS2514 TPS2514A 9 TPS2513, TPS2513A, TPS2514, TPS2514A SLVSBY8D – MAY 2013 – REVISED JUNE 2020 www.ti.com The BC1.2 Specification defines the protocol necessary to allow portable equipment to determine what type of port it is connected to so that it can allot its maximum allowable current drawn. The hand-shaking process is two steps. During step one, the primary detection, the portable equipment outputs a nominal 0.6-V output on its D+ line and reads the voltage input on its D– line. The portable device concludes it is connected to a SDP if the voltage is less than the nominal data detect voltage of 0.3 V. The portable device concludes that it is connected to a Charging Port if the D– voltage is greater than the nominal data detect voltage of 0.3 V and less than 0.8 V. The second step, the secondary detection, is necessary for portable equipment to determine between a CDP and a DCP. The portable device outputs a nominal 0.6-V output on its D– line and reads the voltage input on its D+ line. The portable device concludes it is connected to a CDP if the data line being remains is less than the nominal data detect voltage of 0.3 V. The portable device concludes it is connected to a DCP if the data line being read is greater than the nominal data detect voltage of 0.3 V and less than 0.8 V. 8.2 Functional Block Diagrams S1 DM1 S2 IN Auto-detect S4 DP1 S3 2.7V VDM1 1.2V UVLO S5 DM2 DRIVER S6 S8 Auto-detect GND DP2 S7 2.7V VDM2 1.2V TPS2513: VDM1 / VDM2= 2 V TPS2513A: VDM1 / VDM2= 2.7 V Figure 8.

A USB charger is a device with a DCP, such as a wall adapter or car power adapter. A DCP is identified by the electrical characteristics of its data lines. The following DCP identification circuits are usually used to meet the handshaking detections of different portable devices. 8.3.2 Short the D+ Line to the D– Line The USB BC1.2 Specification and the Chinese Telecommunications Industry Standard YD/T 1591-2009 define that the D+ and D– data lines must be shorted together with a maximum series impedance of 200 Ω. This is shown in Figure 10. D200 Ω (max) D+ GND USB Connector VBUS 5.0 V Figure 10. DCP Short Mode 8.3.3 Divider DCP There are three charging schemes for divider DCP. They are named after Divider 1, Divider 2, and Divider 3 DCPs that are shown in Figure 11, Figure 12, and Figure 13. The Divider 1 charging scheme is used for 5-W adapters, and applies 2 V to the D+ line and 2.7 V to the D– data line. The Divider 2 charging scheme is used for 10-W adapters, and applies 2.7 V on the D+ line and 2 V is applied on the D– line. The Divider 3 charging scheme is used for 12-W adapters, and applies 2.7 V on D+ and D– lines. D+ 2.7 V 2.0 V GND 5.0 V DD+ 2.0 V 2.7 V GND Figure 11. Divider 1 DCP Figure 12.

If a divider device is attached, 2.7 V is applied to the DP pin and 2 V is applied to the DM pin. If a BC1.2-compliant device is attached, the TPS2513 and TPS2514 automatically switches into short mode. If a device compliant with the 1.2 V / 1.2 V charging scheme is attached, 1.2 V is applied on both the DP pin and the DM pin. The functional diagram of DCP auto-detect feature (DM1 and DP1) is shown in Figure 15. DCP auto-detect feature (DM2 and DP2 of TPS2513) has the same functional configuration. For TPS2513A and TPS2514A, the devices also have DCP auto-detect feature and the auto-detect have the same functional configuration expect for the default mode is Divider 3 (D+/D– = 2.7 V / 2.7 V). 5V S1 S2 DM1 D- DP1 D+ S4 GND S3 2.0V 2.7V 1.2 V GND USB Connector VBUS Divider 2 S1, S2: ON S3, S4: OFF Short Mode S4 ON S1, S2, S3: OFF 1.2V on DP1 and DM1 S3, S4: ON S1, S2: OFF TPS2513, TPS2514 Figure 15.

Built-in hysteresis prevents unwanted oscillations due to input voltage drop from large current surges. 8.4 Device Functional Modes The devices operate in DCP mode and automatically monitor the voltage of the USB data lines, and provide the correct electronic signatures on the data lines to charge compliant devices. 12 Submit Documentation Feedback Copyright © 2013–2020, Texas Instruments Incorporated Product Folder Links: TPS2513 TPS2513A TPS2514 TPS2514A TPS2513, TPS2513A, TPS2514, TPS2514A www.ti.com SLVSBY8D – MAY 2013 – REVISED JUNE 2020 9 Applications and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The TPS251xx devices are USB dedicated charging port. The devices only provide the correct electrical signatures on the data lines of USB charger port and do not provide any power for the VBUS.

For 5-W USB charger, the DP1 pin is connected to the D– line and the DM1 pin is connected to the D+ line. This is shown in Figure 16. For 10-W USB charger, the DP1 pin is connected to the D+ line and the DM1 pin is connected to the D– line. This is shown in Figure 17. Table 4 shows different charging schemes for both 5-W and 10-W USB charger solutions. DP2 and DM2 of TPS2513 also provides this two types of connections. Table 4.

If the input supply is placed more than a few inches from the device, an input ceramic bypass capacitor higher than 0.1 µF is recommended. The undervoltage lockout (UVLO) circuit disables DP1, DM1, DP2, and DM2 output voltage until the input voltage reaches the UVLO turnon threshold. 11 Layout 11.1 Layout Guidelines Place the devices near the USB output connector and place the 0.1-µF bypass capacitor near the IN pin. 11.2 Layout Example Figure 22.
