8 Detailed Description
8.1 Overview
The following overview references various industry standards. 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.

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.

8.3 Feature Description
8.3.1 Dedicated Charging Port (DCP)
A dedicated charging port (DCP) is a downstream port on a device that outputs power through a USB connector
but is not capable of enumerating a downstream device, which generally allows portable devices to fast charge at
their maximum rated current. 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.

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.

Feature Description (continued)
8.3.5 DCP Auto-Detect
The devices integrate an auto-detect feature to support divider mode, short mode and 1.2 V / 1.2 V modes. 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).

8.3.6 Undervoltage Lockout (UVLO)
The undervoltage lockout (UVLO) circuit disables DP1, DM1, DP2 and DM2 output voltage until the input voltage
reaches the UVLO turnon threshold. 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.

9.2.2 Detailed Design Procedure
9.2.2.1 Divide Mode Selection of 5-W and 10-W USB Chargers
The TPS2513 and TPS2514 provide two types of connections between the DP pin and the DM pin and between
the D+ data line and the D– data line of the USB connector for a 5-W USB charger and a 10-W USB charger
with a single USB port. 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.

10 Power Supply Recommendations
The devices are designed for a supply-voltage range of 4.5 V ≤ VIN ≤ 5.5 V. 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.
