GENERAL DESCRIPTION

The ADP5061 charger evaluation system is composed of an

evaluation board, an USB A-to-USB Micro B cable, and an USB A

adapter board. All evaluation board functions and circuits are

controlled via one I

C bus connector. The I

C bus interfaces with

the ADP5061 directly, and the digital input/output signals are

controlled through an on-board input/output expander circuit

on the I

C bus. The evaluation board also features a 3.4 V regulator

for VDDIO generation. The board contains jumpers and numerous

test points for easy evaluation.

The ADP5061CB-EVA L Z evaluation kit contains a CD with the

ADP5061 graphical user interface (GUI) Version 3.0 installer.

Use the GUI in conjunction with the USB-SDP-CABLEZ USB

to serial I/O interface.

Full performance details are provided in the ADP5061 data

sheet, and the ADP5061 data sheet should be consulted in

conjunction with this user guide.

Evaluation Board User Guide UG-467 EVALUATION BOARD SOFTWARE INSTALLING ADP5061 EVALUATION SOFTWARE OPERATING THE BOARD WITH THE GUI Before installing the ADP5061 evaluation software, the drivers for the USB-SDP-CABLEZ must be installed. The software and the instructions can be obtained from www.analog.com/USB-SDPCABLEZ. Complete the following steps to use the board: 1. 2. After proper installation of the USB-SDP-CABLEZ drivers, insert the ADP5061CB-EVALZ setup CD and run the Setup.exe.

UG-467 Evaluation Board User Guide BASIC CHARGING PARAMETER SETTINGS The Interrupts & Timers tab (see Figure 3) in the GUI controls the register settings. Register 0x0A is automatically read after every 0.3 second timeout from the last user action involving the GUI. When a certain interrupt is enabled, and there is a status change in the corresponding function during charging, an interrupt message is shown in the Opr Control & Status tab (see Number 3 in Figure 2).

ADP5061 Evaluation Software GUI, Register R/W Tab DIRECT REGISTER READ AND WRITE It is possible to read and write the content of each register using the Register R/W tab as indicated in the GUI. Click READ ALL to update the contents of each register in the GUI. A single register read or write can be done using the controls on the right side of the Register R/W tab of the GUI.

Evaluation Board User Guide UG-467 INPUT CURRENT To measure the VINx current limit, do the following: Measuring Total Input Current (IVIN) 1. 2. 3. When measuring VINx input quiescent currents, take into account that the evaluation board includes an LDO (U1) and I2C input/output (I/O) expander (see U2 and U3A in Figure 8). The LDO generates a 3.4 V VDDIO voltage for the I2C bus and SYS_EN open-drain output, and the I/O expander controls digital inputs DIG_IO1, DIG_IO2, and DIG_IO3.

UG-467 Evaluation Board User Guide FAST CHARGE CURRENT Measuring EOC Current To measure the fast change current, do the following: To measure the EOC current, do the following: 1. 2. 3. 4. 5. 6. Set the VIN supply voltage to 5.0 V. Set VISO_B to 3.9 V. Verify that the GUI Battery Status indicator shows BAT_SNS > Vweak. Set the VINx input current limit to the maximum value 2100 mA. Measure the charge current into the battery. The default value for the fast charge current is 750 mA.

Evaluation Board User Guide UG-467 THR INPUT AND JEITA SETTINGS Evaluating THR Input Using a Trimmer Resistor The THR input of the ADP5061 evaluation board is equipped with two 10 kΩ resistors (R9 and R12) and jumper J10. When using an actual Li-Ion NTC thermistor terminal, configure the board according to Figure 7. It is possible to evaluate the resistance thresholds according to the JEITA Li-Ion battery temperature levels with a 50 kΩ trimmer resistor.
