The ISL81601DEMO2Z demonstration board features the ISL81601 and RL78/G14. The ISL81601 is a 60V high voltage synchronous buck-boost controller. The RL78/G14 is a 28 pin MCU that offers digital control and measurement for charge and discharge functions. The ISL81601DEMO2Z can adjust the input voltage and reverse current for charging, and can also adjust the output voltage and output current for discharging online.The ISL28022 is also used on this board to provide high accuracy voltage and current sensing and report to RL78 with IIC line. The ISL81601DEMO2Z can also report input and output voltage and current with high accuracy.
