Analog Devices / Maxim Integrated MAX49921 Evaluation Kit (MAX49921EVKIT)

Analog Devices MAX49921 Evaluation Kit (MAX49921EVKIT) provides a reference design based on the MAX49921 Current-Sense Amplifier (CSA). The MAX49921 is an AEC-Q100 qualified unidirectional current-sense amplifier optimized for current monitoring of inductive loads, such as DC motors and solenoids, where common-mode voltages can become negative due to inductive kickback, reverse-battery conditions, or transient events.

The Analog Devices MAX49921 Evaluation Kit (MAX49921EVKIT) features a pre-mounted MAX49921 in a 2mm x 3mm, side-wettable TDFN8 package with a gain of 50V/V. Multiple test points enable easy access to all key pin signals.

Features

  • MAX49921 in a TDFN8 package
  • Complete example application circuit
  • Convenient test points
  • Precision real-time current monitoring
  • 0V to +70V input common-mode range
  • Proven PCB layout
  • Fully assembled and tested

Required Equipment

  • DC PS1 (power supply 1 for the IC, 2.7V to 5V, 100mA)
  • DC PS2 (power supply 2 for the common-mode input, up to 70V, 3A)
  • Electronic load (capable of sinking up to 3A and up to 70V)
  • Two digital multimeters (DMMs)
