GENERAL DESCRIPTION

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.
