Product details
Overview
ISL81601DEMO2Z from Renesas Electronics is a demonstration board for bidirectional high-voltage buck-boost power conversion, integrating the ISL81601 controller, RL78G14 MCU, and ISL28022 current/voltage sensor. It supports 9V–60V input, 0.8V–60V output, up to 10A bidirectional current, CC/CV charge/discharge control, and real-time GUI-based online adjustment of voltage/current setpoints.
For engineers reviewing the ISL81601DEMO2Z datasheet, ISL81601DEMO2Z pinout, ISL81601DEMO2Z application, or ISL81601DEMO2Z equivalent, this board enables rapid evaluation of 12V/48V battery charging/discharging, supercapacitor energy management, and high-efficiency bidirectional DC/DC control with digital monitoring via I²C and UART interfaces.
Technical Context
The ISL81601DEMO2Z implements a synchronous four-switch buck-boost topology controlled by the ISL81601 IC, enabling seamless transition between buck (step-down) and boost (step-up) modes without external mode switching. Its RL78G14 MCU handles closed-loop regulation, OCP/OVP/UVP protection coordination, precharge sequencing, and GUI communication via FT232 USB-to-UART bridge.
High-accuracy sensing is achieved using dual ISL28022 current-sense amplifiers with 0.1% gain error and 10ppm/°C drift, reporting input/output voltage and current over I²C to the RL78G14. The board supports dither-enabled EMI reduction and PGOOD status indication, with soft-start and prebias output capability.

FAQ
What is the primary function of the ISL81601DEMO2Z demonstration board?
The ISL81601DEMO2Z demonstration board is a fully assembled, GUI-controlled evaluation platform for the ISL81601 high-voltage synchronous buck-boost controller. It enables engineers to validate bidirectional power conversion-charging batteries/supercaps from a DC source or discharging them to a load-with real-time voltage/current monitoring, CC/CV regulation, and online parameter adjustment. The board integrates the ISL81601, RL78G14 MCU, ISL28022 sensors, and FT232 interface for immediate lab use.
Does the ISL81601DEMO2Z support both charging and discharging modes?
Yes, the ISL81601DEMO2Z supports true bidirectional operation: in Charge mode, it regulates input current/voltage when a higher-voltage DC source is connected to VOUT; in Discharge mode, it regulates output current/voltage when a battery or supercapacitor is connected to VIN. The GUI allows independent setting of input and output CC/CV points, and the board automatically transitions between modes based on terminal voltages and user commands.
How is telemetry data (voltage, current) acquired and reported on the ISL81601DEMO2Z?
Telemetry is acquired using two ISL28022 high-accuracy current-sense amplifiers-one for input (VIN-side) and one for output (VOUT-side)-measuring shunt-based voltage drops with 0.1% gain accuracy. Both sensors report voltage and current values over I²C to the RL78G14 MCU, which aggregates and forwards the data to the PC GUI via the FT232 UART bridge. This architecture enables synchronized, high-fidelity measurement without external instrumentation.
What software and hardware are required to operate the ISL81601DEMO2Z?
A Windows 10 PC with the Renesas-provided GUI software (included with the board), a USB 2.0 cable, and a compatible DC power supply (0–60V, ≥10A) are required. Optional test equipment includes electronic loads (for discharge testing), supercapacitors or batteries, DMMs, and oscilloscopes. No additional programming tools or compilers are needed-the ISL81601DEMO2Z ships with firmware preloaded on the RL78G14 MCU.
Can the ISL81601DEMO2Z be used for precharge sequencing of low-voltage supercapacitors?
Yes, the ISL81601DEMO2Z explicitly supports 0V precharge power-up. When the input voltage is below 10V, the GUI allows setting a negative input current (e.g., –2A) and target input voltage (e.g., 10V) to initiate constant-current charging of the supercapacitor until the CV threshold is reached. This prevents inrush current and ensures safe startup-confirmed in the User's Manual (Rev. 1.00, Sections 2.2–2.3) and demonstrated in Figures 6–7.
