• Microchip products meet the specification contained in their particular Microchip Data Sheet.

• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.

• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.

• Microchip is willing to work with the customer who is concerned about the integrity of their code.

• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Chapter 3. Hardware Description

3.1 UCS1003-1 DEVICE

The UCS1003-1 provides a single USB port power switch for precise control of up to

3.0A continuous current (2.85A typical) with overcurrent limiting, dynamic thermal

management, latch/auto-recovery upon fault, selectable active low or high enable,
under and overvoltage lockout, and back-drive protection.

USB Charging Port profiles are integrated into the UCS1003-1 to ensure compliance
to multiple standards. In addition to power switching and USB Charging Port profiling,
the UCS1003-1 provides automatic and configurable USB data line handshaking to
enable charging of USB-IF Battery Charging 1.2 (CDP or DCP modes), Chinese
Telecommunications Industry Standard YD/T 1591-2009, Apple
other mobile devices.

The UCS1003-1 provides a device attachment detection output, as well as a dedicated
alert output, with current monitoring and charge rationing for controlled delivery of
current regardless of a host’s power state. When the limit is reached, the UCS1003-1
will perform the user-programmed behavior (report and disconnect is the default).

4.2.3 Pin St ate & Attach St atus Panel

4.2.3.1 ALERT# AND A_DET# INDICATORS

When the ALERT# and A_DET# indicators are green, the signals at the device’s
respective pin are low and the corresponding condition has occurred (Alert or Device
attached, respectively). When the indicators are dark, the pin states are high.

4.2.3.2 PIN INDICATORS

The pin indicators (SEL, PWR_EN, M1, M2 and EM_EN) shown in Figure 4-4 are
green if the signal on the corresponding pin on the UCS1003-1 device is high, and dark

if the signal is low. If the “Pin Ignore” box is checked (see Section 4.2.3.3 “Pin

Override”), these indicators will reflect the GUI overrides for these pins.

4.2.3.3 PIN OVERRIDE

For evaluation convenience, the GUI can override the setting of the following pins on
the UCS1003-1 device: PWR_EN, M1, M2 and EM_EN. Check the “Pin Ignore” box
(see Figure 4-4) to enable pin override. Then, check in the corresponding pin box to set
the value high.

Note 1: Pin override does not affect the actual signal on the pin. It only affects the

register values.

2: The SEL pin is only read once by the UCS1003-1 at power up, so there

is no pin override for it. To close the port power switch, the PWR_EN state
must match the SEL state (e.g., SEL = high and PWR_EN = high).

4.3.1.2 CHARGING DOWNSTREAM PORT (CDP)

The CDP charging profile is based on the “USB Battery Charging Specification v1.x”.

When a BC1.x-compliant portable device attachment is detected, the UCS1003-1 and
the portable device do handshaking based on the standard. If handshaking is
successful, charging occurs up to the set current limit.

To select the CDP port power profile, M1, M2 and EM_EN must be all high. This can
be done by removing the jumpers for these pins (from J9 header) or by using the pin

override in the GUI (see Section 4.2.3.3 “Pin Override”).

4.3.1.3 PASS-THROUGH

Data Pass-Through does not apply any type of charger emulation. When selected, it
closes the USB high-speed data switch and supplies current up to the current limit.

To select Data Pass-Through, M1, M2 and EM_EN can be set to any one of the two
DATA PASS-THRU combinations (010 and 110), as shown in Figure 4-9. This can be
done by setting the jumpers for these pins (from J9 header – see

4.3.3.1 CUSTOM EMULATION CONFIGURATION

Creating a custom emulation profile is a two-part process of entering the appropriate
stimulus-response pairs in the provided fields, as well as the desired current limiting
behavior (after emulation is applied, and the portable device starts to draw current).

4.3.3.1.1 Example

Settings shown in Figure 4-12 will apply the Legacy 2 stimulus pair. This includes a
voltage divider on DP and on DM with the values shown under STEP 5 column.

If the portable device draws bus current greater than the charging threshold being
used, it will always operate in Current Limiting Trip mode (with trip point based on the
current limit setting).
