Renesas Electronics Corporation Power Supply Controllers, Monitors ISL28023FR60Z

The ISL28023FR60Z is a precision digital power monitor designed for bidirectional high-side and low-side current sensing and voltage monitoring. It features a serial interface compatible with PMBus, allowing for easy integration into various systems. The device offers high accuracy with a voltage and current monitoring error of just 0.05%, making it suitable for applications requiring precise power management. This power monitor can handle a common-mode input voltage range from 0V to 60V, which is beneficial for telecom, automotive, and industrial applications. It includes an auxiliary input for additional power monitoring and features an 8-bit voltage DAC for DC/DC converter output voltage margining. The ISL28023FR60Z also provides fault indications for overvoltage, undervoltage, and overcurrent conditions, with a fast detection delay of 500ns. Operating across an industrial temperature range of -40¬8C to +125¬8C, the device draws an average current of 800¬µA and is housed in a compact 24-lead QFN package measuring 4mm x 4mm. This combination of features makes the ISL28023FR60Z a versatile choice for engineers looking to implement reliable power monitoring solutions in their designs.
