Description:The ISL28023 is a bidirectional high-side and low-side digital current sense and voltage monitor with a serial interface. The device monitors power supply current, voltage and provides the digital results along with calculated power. The ISL28023 provides tight accuracy of 0. 05% for both voltage and current monitoring. The auxiliary input provides an additional power monitor function. The VCC power can either be externally supplied or internally regulated, which allows the ISL28023 to handle a common-mode
The recommended PCB layout for optimal performance can be found in the ISL28023FR12Z-T7A evaluation board user manual or by contacting Renesas' technical support. Generally, it is recommended to follow good PCB design practices, such as keeping the analog and digital grounds separate, using a solid ground plane, and minimizing noise coupling.
The ISL28023FR12Z-T7A does not require calibration for accurate current measurement. The device has an internal calibration circuit that ensures accurate current measurement. However, it is recommended to follow the application note AN1543 for guidelines on how to optimize the device's performance for specific applications.
The maximum allowable voltage on the VS pin is 36V, as specified in the datasheet. However, it is recommended to operate the device within the recommended operating range of 4.5V to 28V to ensure optimal performance and reliability.
The ISL28023FR12Z-T7A is rated for operation up to 125°C. However, the device's accuracy and reliability may be affected at high temperatures. It is recommended to consult the datasheet and application notes for guidelines on using the device in high-temperature environments.
The ISL28023FR12Z-T7A has an overcurrent detection feature that can be used to detect overcurrent conditions. The device can be configured to generate an alert or shutdown the system in response to an overcurrent event. It is recommended to consult the datasheet and application notes for guidelines on how to implement overcurrent protection using the ISL28023FR12Z-T7A.
