ISL9205xEVAL1Z Evaluation Board Application Manual ® Application Note October 22, 2008 AN1375.1 Description What is Needed The ISL9205xEVAL1Z is an evaluation tool for the ISL9205 single-cell Li-ion battery charger. The evaluation tool provides a complete evaluation platform addressing all data sheet specifications and functionality. The jumpers on the board facilitate the programming of the charge current and different charging conditions. They can also be used to make other necessary connections, such as current measurement. The following instruments will be needed to perform testing: The ISL9205 is a fully integrated single-cell Li-ion battery charger that accepts input voltages ranging from up to 6.5V. After being powered up, the ISL9205 is capable of operating at an input voltage as low as 2.5V. The low operating voltage allows the charger to work with a variety of AC adapters. • Function generator The ISL9205 offers both a 3 package and pinout option and a total of 5 functional variants. The evaluation board accommodates all of these variants. The board provides the pads for 2 package types: the 16 Ld package and the 10 Ld package. On the 10 Ld package option, there are 2 pin functions for pin 9; temperature function (TEMP) and the remote voltage sensing (VSEN) function. Two 0Ω resistors are used to select these functions. Please refer to the ordering information table to order the evaluation board. • Power supplies: - PS1: DC 30V/5A - PS2: DC 20V/5A • DC Electronic load: 20V/5A • Multimeters • Oscilloscope • Cables and wires Quick Setup Guide (Refer to Figure 1) DO NOT APPLY POWER UNTIL STEP 8 Step 1: Connect a 5V supply PS1 to J1 with the current limit set at 1.2A Step 2: Insert a jumper shunt between pins 2 and 3 of J2, as shown in Figure 1 Step 3: Connect a 3.7V supply PS2 to J2 as shown in Figure 1, with the current limit set at 1.2A DESCRIPTION Step 4: Connect the DC electronic load of 1.2A to J2 ISL9205EVAL1Z Evaluation Board for ISL9205 Step 5: Connect amp-meter I2 as shown in Figure 1 ISL9205AEVAL1Z Evaluation Board for ISL9205A Step 6: ISL9205BEVAL1Z Evaluation Board for ISL9205B ISL9205CEVAL1Z Evaluation Board for ISL9205C Insert a thermistor (type 103ET), or a 10k resistor on JP2 to set a valid temperature window ISL9205DEVAL1Z Evaluation Board for ISL9205D Step 7: Switch off all bits of the DIP switch except Bit 9 Step 8: Turn on Power Supplies and DC electronic load Step 9: The green LED should be on, indicating normal charging operation Step 10: The current meter I2 in series with PS2 should read about 90mA as the charging current • Flexible Power Connectors each with a Hook and a Solder Pad Providing Variety to Users Step 11: Switch on Bit 5 of the DIP switch, the current meter I2 should read about 800mA • Convenient Jumpers for Programming the Charge Current, Charge Mode and for Current Measurement Step 12: Switch on both Bit 5 and Bit 6; the current meter I2 should read about 1000mA Ordering Information PART NUMBER Key Features • A Complete Evaluation Platform for the ISL9205 Charger • Accommodates All Package Options • Accepts Input Voltage up to 6.5V • 89mmx65mm Board Size Handy for Evaluation • Six Thermal Vias in the Thermal Pad Similar To Customers’ Thermally Enhanced Environment • On-Board LEDs for Input FAULT and STATUS State Indication 1 CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures. 1-888-INTERSIL or 1-888-468-3774 | Intersil (and design) is a registered trademark of Intersil Americas Inc.

DIP SWITCH BIT DESCRIPTION Jumpers JP1 - A shunt installed on JP1 connects the input source from connector J1 to the circuit if input current measurement is not needed. The shunt can be replaced by a current meter if input current measurement is needed. JP2 - Connection for the thermistor. An industrial standard 103ET type of thermistor or similar type that has a room temperature resistance of 10kΩ should be connected to JP2. If temperature measurement is not needed, a regular 10k resistor can be used to set a valid temperature window. Note that leaving JP2 open will cause the charge to shut down. DIP Switch Settings A 9-bit DIP switch is provided to set up current reference, end-of-charge (EOC) current, and so on. The functionality of the bits are described in Table 1. TABLE 1. JUMPER SETTINGS JUMPER FUNCTION JP1 Connect the input power at J1 to VIN pin JP2 For thermistor connection JP3 Connects VBAT to connector J2 JP3 - A shunt installed on JP3 connects the VBAT pin to the output connector J2 if output current measurement is not needed. The shunt can be replaced by a current meter if output current measurement is needed. 2 AN1375.1 October 22, 2008 Application Note 1375 TABLE 2.
