PI5USB1458A

USB Host Charger Controller supporting BC1.2,

YD/T-1591, & Non-standard Protocols

Features

Description

Notebook PCs are used around the world to charge battery-pow-

ꢀÎManages communication to allow charging to occur

ꢀÎProvides multiple modes of charging to ensure all of the

ered handheld devices such as cell phones, tablets and MP3/MP4

players. Hand-held devices require communication with the

notebook PC before they start to draw current. is ensures that

the handheld device will obtain suﬃcient current when it wants

to charge. e challenge is that notebook PC's do not provide

acknowledge signal to the handheld device when the notebook

is in “Sleep” mode.

following specs can be met:

à DCP, CDP, and SDP per BC1.0, 1.1, 1.2 spec

à DCP per YD/T-1591 spec

à Samsung fast charging

à Sony Ericsson fast charging

à Apple fast charging 1A and 2A

à Amazon Kindle Fire

ꢀÎAutomatic USB Device Identiﬁcation Circuit (used to

determine charging mode required)

ꢀÎSingle Power Supply, 5V 5%

ꢀÎ-40^oC to +85^oC Operating Temperature Range

Pericom’s PI5USB1458(/A) solves this issue by setting the

D+/D- pins in the notebook PC to the required signal levels dur-

ing “sleep” mode. When the handheld device sees these required

signal levels, it will then start to draw the current required to

charge itself.

ꢀÎIntegrated ESD protection up to +/- 4kV contact on pins

Cell phones within today’s market use diﬀerent communication

schemes, so the switch will need to conﬁgure itself in diﬀerent

modes. PI5USB1458 (/A) can alternate between modes automati-

cally, once device type is correctly detected.

2 and 3 per IEC61000-4-2 spec

ꢀÎDetects and diﬀerentiates between High-Speed devices and

mouse/keyboard (USB Low/Full Speed device) when in Auto

dedicated charging mode

ꢀÎAnti-loop protection for hard disk drive (HDD)

ꢀÎPackaging (Pb-free & Green):

D+, D- are protected with Pericom’s ESD protection circuits sup-

porting ESD damage as high as +/-4kV contact per IEC61000-4-2

speciﬁcation.

USB Host Charger Controller IC PI5USB1458A

Detailed Feature Description

Auto Dedicated Charging Mode enabled

When the PI5USB1458 (/A) is conﬁgured into auto mode with Auto dedicated charging mode enabled (see truth table to under-

stand how to conﬁgure into auto mode), the charger controller will manage all communication with external devices to enable

charging to occur. First, Pericom’s IC will use load sensing techniques to detect when a device has been plugged in.

Once a device is properly detected, the Pericom IC will automatically switch to the appropriate charging mode required for the

speciﬁc external USB device that was detected.

Mouse/Keyboard pass through mode Explanation

Today’s systems are enabled to wake up from S3 mode if a pre-enumerated mouse/keyboard has activity (movement or key-pressed).

In order for the system to continue supporting this feature, the USB host controller must be able to communicate with the external

device in S3 mode. erefore, if a mouse/keyboard is detected (via the USB low-speed/ full-speed pass through feature), Pericom’s

PI5USB1458 family will enable the communication between device and controller. Our device will automatically pass the signals

through with minimal degradation.

Once SB/ signal goes from high to low (indicating system has changed from S0 to S3), Pericom's device will detect the external USB

device. If the device is detected as a mouse or keyboard (determined by looking at USB data-rate) we will ensure the connection

between the USB device and USB host remains in place.

Anti-Loop protection for HDD

is circuit prevents hard disk drive from turning on and oﬀ continously.

Auto Dedicated Charger mode description

During Pericom's Auto dedicated charger mode, we automatically detect and enable DCP charging modes for all popular USB

devices on the market.

DCP stands for Dedicated Charging Port. Per the Battery Charging Spec, DCP is described as a host charging mode whereas only

charging is allowed. Data transfer through USB, during DCP mode is not allowed. Per the Battery Charging Spec, the host charger

must short D+ to D-, and in turn the USB device will draw up to 1.5A.

Since the release of the Battery Charging Spec, certain mobile phone and tablet OEMs have released products with unique dedicated

charging modes. When Pericom's Auto dedicated charger mode is enabled, we can automatically switch between dedicated charging

modes per the Battery charging spec or other dedicated charging modes supported by speciﬁc OEMs.

CDP mode description

Charging Downstream Port (CDP) is the communication protocol found in host chargers capable of supplying up to 1.5A current to

charge external USB devices. e communication scheme is deﬁned clearly in the USB Battery Charging Spec 1.2. A CDP link can

allow USB data to be transferred between the host charger and the external device as well as allow charging to occur. e actual

current draw is managed by the external device while the CDP only limits the max current draw to 1.5A. Pericom is able to fully

support this communication, which includes both a primary and secondary detection procedure.

BC 1.2 Suspend Charging (DCP)

e suspend-charge (DCP) mode deﬁned in BC 1.2 is a manual-DCP-mode, is not exactly the same as the auto suspend-charge

mode in PI5USB1458. In order to oﬀer an accurate BC 1.2 suspend-charge (DCP) mode apply: "SB/" to 1 and “SEL” pin with 1.25V,

Power-oﬀ, then aꢀer re-power-on PI5USB1458/A.
