The ISL28130ISENSEV1Z, ISL28133CSENSEV1Z, ISL28133ISENSEV1Z, and ISL28134ISENSEV1Z evaluation boards are designed specifically for low-side bidirectional current sensing up to 10A of current. The evaluation boards use a 1mΩ current sense resistor that is capable of handling 4W of power dissipation. These evaluation boards are separated into three categories: low cost (ISL28130ISENSEV1Z), low power (ISL28133CSENSEV1Z, ISL28133ISENSEV1Z) and low noise (ISL28134ISENSEV1Z).

The ISL28133CSENSEV1Z is designed specifically for low-side current sensing applications with up to 10A of current, while the ISL28133ISENSEV1Z uses the ISL28133 chopper amplifier in a high side, low side of floating supply current sense application.
