Features
Description
ÎÎManages communication to allow charging to occur
Notebook PCs are used around the world to charge battery-powered 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. This ensures that
the handheld device will obtain sufficient current when it wants
to charge. The challenge is that notebook PC's do not provide
acknowledge signal to the handheld device when the notebook
is in “Sleep” mode.
ÎÎProvides multiple modes of charging to ensure all of the
following specs can be met:
àà DCP, CDP, and SDP per BC1.0, 1.1, 1.2 spec
àà DCP per YD/T-1591 spec
àà Samsung fast charging
àà Sony Ericsson fast charging
àà Apple fast charging 1A and 2A
àà Amazon Kindle Fire
ÎÎAutomatic USB Device Identification Circuit (used to
determine charging mode required)
ÎÎSingle Power Supply, 5V ±5%
Pericom’s PI5USB1458(/A) solves this issue by setting the
D+/D- pins in the notebook PC to the required signal levels during “sleep” mode. When the handheld device sees these required
signal levels, it will then start to draw the current required to
charge itself.
ÎÎ-40oC to +85o C Operating Temperature Range
ÎÎIntegrated 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 automatically, once device type is correctly detected.
2 and 3 per IEC61000-4-2 spec
ÎÎDetects and differentiates between High-Speed devices and
mouse/keyboard (USB Low/Full Speed device) when in Auto
dedicated charging mode
ÎÎAnti-loop protection for hard disk drive (HDD)
ÎÎPackaging (Pb-free & Green):
D+, D- are protected with Pericom’s ESD protection circuits supporting 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 understand 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. Therefore, 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
This 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. The 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. The 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)
The 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 after re-power-on PI5USB1458/A.
