Infineon Technologies IRS2007S | Demoboard EVAL-PS-IRS200x-OM30118SB

Description

The power stage of the evaluation board EVAL-PS-IRS200x-OM30118SB consists of four phases with individual leg shunt, which is a popular topology for stepper motor driving. The input voltage 24~72 VDC is available for most of the stepper motors on the market. The MOSFETs are selected with IPP180N10N3 G (100 V/18 mΩ), and driven by the 200 V series PNJ gate drivers IRS2005S/IRS2007S/IRS2008S accordingly. Each phase leg current is sensed by the leg shunt, and exported to the control interface in differential mode. The board can run a stepper motor by connecting to an external controller. The board is originally soldered with the IRS2005S (positive logic inputs), and can be replaced by two other parts with the same footprint for different logic inputs (refer to Table 5). The board is available via regular Infineon distribution partners as well as on Infineon's website. The features of this board are described in Chapter 3 of this document. The remaining sections provide information to enable customers to copy, modify and qualify the design for production according to their own specific requirements. Environmental conditions were considered in the design of the EVAL-PS-IRS200x-OM30118SB. However, the board has not been qualified in terms of safety requirements, manufacturing and operation over the entire operating temperature range or lifetime. The boards provided by Infineon are subject to functional testing only. Figure 1 depicts the block diagram of the EVAL-PS-IRS200x-OM30118SB. The shaded parts are those contained in the PCB. The auxiliary power supply VCC has to come from the external input.
