The Analog Devices LTC1921CS8#PBF is an integrated dual -48V supply and fuse monitor featuring current and power monitors and regulators. It monitors and regulates the current and power of two -48V systems. Its low cost and low power design make it suitable for high-density system designs. The LTC1921CS8#PBF includes two integrated high-side current and power monitors, two low-side current and power monitors, and a wide range of fault protection functions including overcurrent, undercurrent, overvoltage, and device over-temperature detections. The dual power monitor synchronizes two independent -48V systems, enabling the device to accurately track up/down transitions. Additionally, its low total power consumption makes it suitable for point-of-load applications.
