• 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.”

Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digit al M illennium Copyright Act. If such acts

Installation and Operation

2.1.3 Configuration for Dedicated Charger Emulation (DCE) Mode

The Dedicated Charger Emulation (DCE) mode configures the UCS1003-2
Evaluation Board to cycle through emulation profiles until the charging current
increases above the threshold of 175 mA. T o configure the evaluation board for
the DCE mode, follow these steps:

1. Configure the jumper settings as shown in Table 2-2.

2. Apply 5V. The UCS1003-2 is set to the Detect state and awaits a

downstream device attachment.

3. Connect a tablet or a cell phone to the USB port J10.

When a charger emulation profile is applied and the charging current increases
above 175 mA, LD2 (labeled CHRG) will illuminate and charging will continue.

Chapter 3. Hardware Overview

3.1 INTRODUCTION

The UCS1003-2 Evaluation Board provides the means to demonstrate all of the
UCS1003-2 functionality. The LEDs indicate the status information.

3.1.1 Power Source

The UCS1003-2 Evaluation Board requires 5V, 3.0A. It has two power supply
connectors:

• J6 jack for AC-DC wall adapters

• J4 for connection with wires from a laboratory power supply
The board allows using only one of these power supplies or both (for the evaluating split

supply feature).
According to the note from the Electrical Characteristics table from the data sheet, for

split supply systems using the Attach Detection feature, the V

UCS1003-2 Evaluation Board User’s Guide

3.2 STAND-ALONE FUNCTIONALITY

The UCS1003-2 is intended for the stand-alone USB charger and BC1.2 CDP, DCP
and SDP applications. The green LED (LD2 – CHRG) indicates that the charging
current has exceeded the 175 mA threshold (I

See Table 2-1 for the description of jumpers.

3.2.1 Charger Emulation Mode Configurations

The Charger Emulation mode of the UCS1003-2 is controlled by the pin states: M1, M2
and EM_EN. These are the jumpers located on the J11 header.

3.2.2 Attach Detection and Power States

The UCS1003-2 can use the attach detection functionality or force the Active mode
power state. This is controlled by jumper J14, position 3-4.

3.3 FAULT HANDLING

The UCS1003-2 has two modes of Fault handling that can be configured for the LATCH
upon Fault or auto-recovery. Jumper J14, position 1-2, selects the Fault handling.
When a Fault condition is detected, the red LED (marked as LD1 – ALERT) turns on.

See Table 2-1 for the description of jumpers.

BUS_CHG

).

3.4 CURRENT LIMITING

The UCS1003-2 is capable of eight selectable current limits (see the “UCS1003-1/2/3
Data Sheet” for detailed information). Jumper J13 selects the current-limiting value.

See Table 2-1 for the description of jumpers.

3.5 HIGH-SPEED USB DATA SWITCH

The UCS1003-2 contains a series of USB 2.0-compliant high-speed switch between
the DP and DM input and output pins. This switch is functional in CDP, SDP and USB
pass-through configurations. When used in one of these configurations, a port from a
PC must be connected to the J9 USB connector.
