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.
