PXI multi-cell battery simulator modules
Comment I
enable direct voltage and current readback either programmatically or using Pickering's soft panel control. Each cell simulator is highly accurate, specified at ±5mV from 1V to 7V. The new battery simulator
P
modules occupy a single PXI slot. They are available with two, four or six battery cell simulators per module that are fully isolated from ground and from each other facilitating series connection to simulate batteries in a stacked architecture. The 750V isolation barrier allows the modules to be used to simulate lower power battery stacks that are commonly used for vehicle propulsion. Battery charging emulation is available up to 100mA. Each cell provides
independent power and sense connections, allowing the simulator to sense a remote load and correct for wiring losses. The battery simulator is designed to respond to dynamic loads, minimising the need for local decoupling capacitors at the load. The module can also independently read the voltage at the load (via sense lines) and output current for each cell.

Enclosed power supply
Toshiba release new 40V/2.0A constant current stepper motor driver IC
constant current motor control without the need for an external current sense resistor. The new TB67S539FTG is housed in a 5.0mm x 5.0mm QFN32 package and

anless operation for long- term system availability is a special design feature
with bottom plate cooling that supports heat dissipation in RECOM‘s RACM1200-V power supply and enables continuous output power of up to 1000W. In boost mode, up to 1200 watts of output power is available through the unit for up to 10 seconds, or for longer periods with sufficient system airflow. A wide range of output voltage settings and a combination of constant current limiting and hiccup mode settings make the power supply versatile in medical and industrial environments, especially in applications that
do not allow for a fan.

is suited to a wide range of constant current control stepper motor applications including those found in office automation, commercial and industrial equipment. The device is also suited for use in surveillance cameras and projectors. Based upon Toshiba’s latest BiCD process, the new product is
capable of driving bipolar stepping motors at voltages up to 40V and currents up to 2.0A. The integrated H-bridge circuit for motor control uses an Nch/Nch configuration and has a built-in charge pump circuit for output stage control. The current detector is integrated within the QFN32 package,
removing the need for an external current sense resistor. In addition, the TB67S539FTG does not require an external capacitor for the charge pump as it is also integrated. With this high level of integration, the need for PCB space is significantly reduced. The output stage (covering the upper and lower transistor) has
an RDS(ON) of just 0.8 Ohm, ensuring efficient operation and reducing heat generation during use. When in sleep mode, the device draws a maximum current of 1µA. Alongside the stepping motor IC, a new, compact add-on
board is also available. Created in partnership with Mikroe, the Stepper 17 Click board is supported by a mikroSDK compliant
library, with functions that simplify software development.

changes. The addition of NXP's Kinetis family takes
the number of MCUs supported by mikroSDK 2.0 to over 1500, ranging from small 8bit to 32bit devices. Other notable product families covered include PIC and PIC32 by Microchip and the 849-strong STM32 family from STMicroelectronics. New devices and
architectures are being added all the time. mikroSDK 2.0 is a complete, cross-
platform software development kit for embedded applications providing everything necessary to start developing, and prototyping, including Click board applications and GUIs for embedded devices.
