MAX40056T Datasheet Bidirectional Current Sense Amplifier

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Click here for production status of specific part numbers. MAX40056F/ MAX40056T/ MAX40056U EVALUATION KIT AVAILABLE Bidirectional Current Sense Amplifier with PWM-Rejection.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX40056 is a bidirectional current-sense amplifier with an input mon-mode range that extends from -0.1V to +65V together with protection against negative inductive kickback voltages to -5V.

This CSA is well-suited for phase current monitoring of inductive loads, such as motors and solenoids, where pulse width modulation is used to control the drive voltage and current.

The MAX40056 uses an improved technique to help reject mon-mode input PWM edges with slew rates up to and beyond ±500V/µs.

Key Features

  • Fast, 2μs PWM Edge recovery (1%) from 500V/μs PWM Edges.
  • 60dB AC CMRR Rejection at 50V, ±500V/μs PWM Edges.
  • 140dB DC CMRR Rejection.
  • -0.1V to +65V Input Voltage Range.
  • -5V to +70V Protective Immunity.
  • 300kHz, -3dB Bandwidth.
  • Multiple Gain Options; 10V/V, 20V/V, 50V/V.
  • Internal, 1% Reference for Bidirectional Offset.
  • 5μV (Typ) Input Offset Voltage.
  • Rail-to-Rail Output.
  • 2.02mm x 1.4mm WLP-8 and 8-pin μMAX.
  • -40°C to +125°C Temperature Ran.
