Description
AI
The LT9890 is a high-precision current monitor with an internal current-sense element supporting up to 150 A of load current. Factory calibration of the current-sense element and a zero temperature coefficient architecture results in less than 1.3% total unadjusted error (TUE). A 26,600:1 input-to-output current ratio with a response bandwidth greater than 3 MHz provides a fast and accurate ground-referenced output signal while being insensitive to ground voltage variations. Minimal power loss is achieved through a low, 150 μΩ current-path resistance and an aspect ratio conducive to wide printed circuit board (PCB) traces. Input voltages from 2.7 V to 65 V are supported. The LT9890 is compatible with the Intel Psys (platform power) applications.ApplicationsComputers and network serversIntel central processing unit (CPU) motherboardsNetwork storageCommunication equipmentElectric vehiclesPhotovoltaics
