USERS MANUAL ISL28022EVKIT1Z AN1875 Rev 3.00 ISL28022 Digital Power Monitor Evaluation Kit February 17, 2016 R Board (ISL28022DBEV1Z) Introduction LOAD nd The 2 DPM evaluation kit board is the R board. The LOAD The ISL28022 Digital Power Monitor (DPM) evaluation kit is a purpose of the R board is to exercise the three supplies LOAD three evaluation board design that demonstrates the sourced by the dongle board. The R board also allows the LOAD functionality of the ISL28022. By design, the ISL28022 is user to source power to a user defined system via a jumper considered a digital helper for a variety of applications ranging selection. The R board has a programmable load resistor. LOAD from energy optimization to diagnostics of complex systems. The programmable load resistor is a ISL23345 digitally The three board evaluation kit demonstrates the functionality controlled potentiometer (DCP). The evaluation software of the DPM for three specific applications while offering a allows the user to configure the DCP for monitoring power. The configurable board for users to connect to their systems. R board connects to the dongle board to demonstrate the LOAD The DPM Evaluation kit is accompanied by a graphical user functionality of the ISL28022. interface (GUI) that allows the user to configure the ISL28022 for monitoring bus voltage and current in a specific ISL28022 Generic Board (ISL28022MBEV1Z) application. The GUI has a data save feature allowing the The final ISL28022 board is a non-configured ISL28022 that transfer of measurement data to another software application connects the analog inputs to the outside world. The board for analysis. allows a user to build a system that requires either current or power monitoring around the ISL28022. The analog inputs Dongle Evaluation Board (ISL28022USBEV1Z) (VINP, VINM and VBUS) of the ISL28022 accept input voltages The ISL28022 DPM evaluation kit consists of three boards a ranging from 0V to 60V. The ISL28022 allows the user to dongle, a generic ISL28022 board, and a R board. The LOAD uniquely configure the slave address via jumper selections. dongle board mates from a PC to the ISL28022 via a The ISL28022 can be powered from a user defined source or microcontroller. The microcontroller converts USB commands the 3.3V supply generated from the USB voltage. The 2 2 sourced from the PC to an I C header. The I C pins (SCL and SDA) acceptable power supply voltage range for the ISL28022 is are connected to the right angle header at the edge of the board. from 3V to 5.5V. The external clock/interrupt pin is routed to The dongle board has three circuits that convert the USB supply the outside world via a jumper selection. The maximum voltage from 5V to 3.3V, 12V and a selectable point of load (POL) measurable input differential (VINP - VINM) is 300mV. The voltage. Each voltage translation circuit has a ISL28022 differential voltage between the VINP and VINM pins can connected to monitor the current sourced by the supply. Each withstand a magnitude of 60V. The differential supply circuit has been optimized to measure 100mA at full scale. The tolerance allows for the debug of catastrophic circuit events. three supply voltages are routed to the right angle connector 2 along with the I C pins, SDA and SCL.
