UNIVERSAL SERIAL BUS INTERFACES FOR DATA AND POWER –
Part 3: USB Battery Charging Specification, Revision 1.2
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The IEC 62680 series is based on a series of specifications that were originally developed by
the USB Implementers Forum (USB-IF). These specifications were submitted to the IEC under
the auspices of a special agreement between the IEC and the USB-IF.
The USB Implementers Forum, Inc. (USB-IF) is a non-profit corporation founded by the group
of companies that developed the Universal Serial Bus specification. The USB-IF was formed
to provide a support organization and forum for the advancement and adoption of Universal
Serial Bus technology. The Forum facilitates the development of high-quality compatible USB
peripherals (devices), and promotes the benefits of USB and the quality of products that have
passed compliance testing.
ANY USB SPECIFICATIONS ARE PROVIDED TO YOU "AS IS, "WITH NO WARRANTIES
WHATSOEVER, INCLUDING ANY WARRANTY OF MERCHANTABILITY, NON-
INFRINGEMENT, OR FITNESS FOR ANY PARTICULAR PURPOSE. THE USB
IMPLEMENTERS FORUM AND THE AUTHORS OF ANY USB SPECIFICATIONS DISCLAIM
ALL LIABILITY, INCLUDING LIABILITY FOR INFRINGEMENT OF ANY PROPRIETARY
RIGHTS, RELATING TO USE OR IMPLEMENTATION OR INFORMATION IN THIS
SPECIFICAITON.
THE PROVISION OF ANY USB SPECIFICATIONS TO YOU DOES NOT PROVIDE YOU
WITH ANY LICENSE, EXPRESS OR IMPLIED, BY ESTOPPEL OR OTHERWISE, TO ANY
INTELLECTUAL PROPERTY RIGHTS.
Entering into USB Adopters Agreements may, however, allow a signing company to
participate in a reciprocal, royalty-free licensing arrangement for compliant products. For

Adam Burns
to BC1.2, unless BC1.1 is specifically indicated.
1. Allow DCPs to output more than 1.5A. Allows
Portable Devices (PDs) with switch mode chargers to
draw more power. Section 4.4.1.
2. Increase minimum CDP current to 1.5A. Without
change, PDs had to draw less than 500mA, to avoid
CDP shutdown. Table 5-2.
3. Indicate that ICDP max and IDCP max limits of 5A
come from USB 2.0, and are safety limits. Table 5-2
note 1.
4. Allow PDs to draw up to 1.5A during HS chirp and
traffic. Remove previous limits of 560mA and 900mA
which was based on HS common mode ranges. Section
3.5.
5. Require CDPs to support 1.5A during HS chirp and
traffic. Affects CDP common mode range. Section 3.5.
6. Reduce maximum PD current from 1.8A to 1.5A, to
avoid shutdown when attached to CDP. Table 5-2.
7. Rename Docking Station to ACA-Dock, to avoid
confusion with other types of Docking Stations.
8. Require ACA-Dock to differentiate itself from an ACA,
by enabling VDM_SRC during no activity. Section
3.2.4.4.
9. Allow CDP to leave VDM_SRC enabled while
peripheral not connected. Section 3.2.4.2.
10. Remove ICHG_SHTDWN. This was a recommended
max output current for Charging Ports with VBUS
grounded. BC1.1 Section 4.1.
11. Require VDP_SRC to not pull D+ below 2.2V when
D+ is being pulled to VDP_UP through RDP_UP.
Require VDM_SRC to not pull D- below 2.2V when D- is
being pulled high. Required for ACA-Dock support.
Table 5-1 notes 1 and 2.
12. Make DCD current source optional for PDs. Section
3.2.3.
13. Make DCD timeout required for PDs. Section 3.2.3.
14. Make Secondary Detection optional for PDs. Section
4.6.2.
15. Make Good Battery Algorithm required behavior for
PDs. Section 3.2.4.
16. Remove resistive detection. BC1.1 Section 3.9.
17. Change PD Required Operating Range to include
4.5V at 500mA. Figure 4-3.
18. Allow any downstream port to act as a DCP. Section
4.1.3.
19. Require PDs to enable VDP_SRC or RDP_PU when
charging from a DCP. Section 3.3.2.
20. Allow chargers to renegotiate current with PD by
dropping and reasserting VBUS. Section 4.1.3.
