LT9890 Datasheet 150a Current Monitor

Manufacturer: Analog Devices

Overview: Data Sheet LT9890 150 A Current Monitor for Intel Psys Applications.

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.

Key Features

  • Integrated current sense element.
  • 150 A current range.
  • 26,600:1 input-to-output current ratio (5 mA at 133 A).
  • ±1.3% TUE maximum (ISENSE = 45 A to 150 A).
  • 3.2 MHz small-signal bandwidth (ISENSE = 150 A).
  • 150 μΩ current path resistance.
  • Powered from 2.7 V to 65 V.
  • Intel Psys compatible.
  • Available in 108-terminal, 10 mm × 20 mm × 2.75 mm, LGA package.
