Intersil ISL9238EVAL1Z Battery Charger Evaluation Board is designed to demonstrate the performance of the ISL9238. The ISL9238 is a buck-boost Narrow Output Voltage DC (NVDC) charger. The default value numbers of the battery in series, the switching frequency and the adapter current limit charging function can be programmed by the resistor from the PROG pin to GND. Those values also can be set by SMBus.

The is a buck-boost Narrow Output Voltage DC (NVDC) charger utilizing Intersil's advanced R3TM Technology to provide high light-load efficiency, fast transient response and seamless DCM/CCM transitions for a variety of mobile and industrial applications. In Charge mode, the ISL9238 takes input power from a wide range of DC power sources (conventional AC/DC charger adapters, USB PD ports, travel adapters, etc.) and safely charges battery packs with to 4 cells in a series configuration. The ISL9238 supports On-the-Go (OTG) function for 2- and 4-cell battery applications. When OTG function is enabled, the ISL9238 operates in the Reverse Buck mode to provide 5V at the USB port. The ISL9238 has serial communication via SMBus/I2C that allows programming of many critical parameters to deliver a customized solution. These programming parameters include, but are not limited to: adapter current limit, charger current limit, system voltage setting and trickle charging current limit. The ISL9238EVAL1Z evaluation board is designed to demonstrate the performance of the ISL9238. The default value numbers of the battery in series, the switching frequency and the adapter current limit charging function can be programmed by the resistor from the PROG pin to GND. Those values also can be set by SMBus.

to 25V power supply with at least 6A source current capability Electronic load capable of sinking current to 6A Battery emulator capable of sinking and sourcing current to 6A Digital Multimeters (DMMs) 100MHz quad-trace oscilloscope
NOTE: Customers can use a power supply (which can source but cannot sink current) in parallel with an e-load Constant Current (CC) mode to emulate the battery. For example, for charging, set the charging current command lower than the CC mode e-load. If the e-load CC mode current is set at 3A, the charge current command is 2A, then the e-load will take 2A from the charger and take another 1A from the power supply in parallel with it. For discharging, the power supply is just like the battery to discharge current. The customer can also use the e-load Constant Voltage (CV) mode to emulate the battery to take the charging current from the charger and set the e-load CV voltage below the MaxSysV register setting, however, this e-load CV mode cannot source current like a battery.
Three LEDs are indicating ACOK, PROCHOT and OTGPG/CMOUT status, respectively. For more details about the functions of these three pins, refer to the ISL9238 datasheet. Follow these steps to evaluate the ISL9238 key functions,including system voltage regulation, input current limit regulation, Charging mode, trickle Charging mode and OTG mode. Figure 3, which is the top view of the evaluation board, highlights the key testing points and connection terminals. For other modes or more information about ISL9238, please refer to the ISL9238 datasheet.
1. Set the power supply to 5V and, with the output disabled, connect the to J1 and the end J2. 2. Ensure jumpers JP3, JP4 and JP6 are shorted. SW1 and SW2 should switch to the low position. 3. Turn on the power supply,measure VSYS using the DMM across and TP5. VSYS should read 8.38V. The current meter on the supply should read <100mA.Increase VIN from to 15V slowly. Monitor PH1 and PH2 to observe seamless switching from Boost mode to Buck-Boost mode and finally into Buck mode.
The ISL9238EVAL1Z provides all circuits that are required to evaluate the features of the ISL9238. A majority of the features of the ISL9238, such as adjustable output voltage, On-the-Go (OTG) mode, Trickle Charging mode for depleted battery, and system power monitor at buck, Boost and Buck-Boost modes are available on this evaluation board.
1. Keep VIN as a constant value between 3.8V and 24V. Set the battery emulator voltage to 7.8V, connect the battery emulator output to battery leads,J5 and J6. Then, turn on the battery emulator; there is no charge and discharge current for the battery, which is consistent to the BGATE signal of a high voltage level. 2. Add an electrical load on VSYS and GND terminals, J3 and J4. Turn on the load and increase the electrical load slowly; the input current increases correspondingly and VSYS keeps stable at 8.38V. The output voltage (VSYS) will start dropping as the input current reaches the 1.5A input current limit. For the input current limit details, refer to the ISL9238 datasheet. If the VSYS voltage is 150mV lower than the battery voltage, BGATE FET will turn at a low voltage level such that the battery supplies the current to the load.
The number of battery cell and adapter current limit default values can be configured with a standard 1% 0603 resistor (R23) from the PROG pin to GND. The "PROG PIN PROGRAMMING OPTIONS" table in the ISL9238 datasheet shows the programing options. After the default number of cells in series are set, the default values for MaxSystemVoltage and MinSystemVoltage are set accordingly. These values can also be changed through the SMBus control registers, which are implemented with the Intersil GUI, shown in Figure 2 on page 3.
