The ADuM7223 is a 4A isolated, half-bridge gate driver that employ Analog Devices, Inc.’s iCoupler® technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and non-isolated gate drivers. By integrating the isolator and driver in a single package, propagation delay is a maximum of only 60 ns and the propagation skew from channel to channel is a maximum of only 7ns.The ADuM7223 provides two independent isolation channels.

The ADuM7223 operates with an input supply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. The outputs operate in a wide range from 4.5V to 18V with three output voltage versions available. The 5 × 5 mm, LGA package provides 565 V operating voltage from input to output and 700 V from output to output.

In comparison to gate drivers employing high voltage level translation methodologies, these gate drivers offer the benefit of true, galvanic isolation between the input and each output. As a result, these gate drivers provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.

Product Detail

The EVAL-ADUM7223EBZ supports the ADuM7223 isolated precision half-bridge driver. Because the evaluation boards have footprints for IGBTs and MOSFETs in TO-252 packages, the ADuM7223 can be evaluated with many different power devices. The evaluation boards also allow the high-side supply to be bootstrapped to the low-side supply.

Features and Benefits

This evaluation board is obsolete and no longer recommended.


The FMCMOTCON2 evaluation kit enables users to:

  • Model and implement motor control algorithms rapidly for high performance servo systems, incorporating system modelling and design concepts using Mathworks model based design
  • Reduce time needed to move a motor control system from concept to production, by providing a prototyping system to verify the hardware and control algorithms before moving to production stage.

Product Detail

This evaluation board is obsolete and no longer recommended.


The AD-FMCMOTCON2-EBZ is a complete high performance servo system on an FPGA Mezzanine Card (FMC) board, the purpose of which is to provide a complete motor drive system demonstrating efficient and high dynamic control of three phase PMSM and induction motors up to 48V and 20A.

Two motors can be driven at the same time, each motor having its separate power supply. The system incorporates high quality power sources; reliable power, control, and feedback signals isolation; accurate measurement of motor current & voltage signals; high speed interfaces for control signals to allow fast controller response; industrial Ethernet high speed interfaces; single ended Hall, differential Hall, encoder and resolver interfaces; digital position sensors interface; flexible control with a FPGA/SoC interface.

The kit consists of two boards: a controller board and a drive board. An optional AD-DYNO2-EBZ dynamometer can also be purchased through Avnet and is intended to be an extension of the drive system.

Controller Board

  • Digital board for interfacing with the low and high voltage drive boards
  • Compatible with all Xilinx FPGA platforms with FMC LPC or HPC connectors
  • FMC signals voltage adaptation interface for seamless operation on all FMC voltage levels
  • Fully isolated digital control and feedback signals
  • Isolated Xilinx XADC interface
  • 2 x Gbit Ethernet PHYs for high speed industrial communication, with 3rd party EtherCAT support
  • Single ended Hall, Differential Hall, Encoder, Resolver interfaces
  • Digital sensors interfaces
    • EnDat
    • BISS Interface

Drive Board

  • Drives motors up to 48V @ 20A
  • Drives 2 motors simultaneously
  • High frequency drive stage implemented with ADI isolated gate drivers
  • Supported motor types
    BLDC
    PMSM
    Brushed DC
    Stepper (bipolar / unipolar)
  • Integrated over current protection
  • Reverse voltage protection
  • Current and Voltage measurement using isolated ADCs
  • BEMF zero cross detection for sensorless control of PMSM or BLDC motors
  • Separate voltage supplies for the 2 motors so that the motors don't influence each other

Dynamometer System with Embedded Control

  • Two BLDC motors connected by a rigid couple in a dyno setup, which can be used to test real-time motor control performance.
  • One BLDC motor acts as an electronically adjustable load and is driven by the embedded control system. This motor can be directly connected to the FMC motor drive to get complex / active loads. The load can be driven also by the AD-FMCMOTCON2-EBZ to implement dynamic load profiles.
  • The other BLDC motor is driven by the FMC motor drive.
  • Measurement and display of load motor current
  • Measurement and display of load motor speed
  • External control using Analog Discovery and MathWorks Instrumentation Control Toolbox

Software:

Example reference designs showing how to use the platform with Xilinx® FPGAs or SoCs and high performance control algorithms from Mathworks® are provided together with the hardware. Information on the FMC board, and how to use it, the design package that surrounds it, and the software which can make it work, can be found by clicking the software link.
