NV705223R1DBGEVB: Daughterboard SPI Stepper Driver with Voltage Regulator (NQFP) Evaluation Board Evaluation Board Description The NV705223R1DBGEVB is a form factor Reference Design for driving bipolar stepper motors. The reference design can be interfaced via I/O pins and the SPI bus to an external microcontroller. In conjunction with the NCV7052xGEVK evaluation kit it forms a complete solution turning high level commands from a CAN node in well defined motions. The design incorporates the lowest bill of materials, small board size and perfect matched thermal resistance allowing to drive 800 mA at elevated ambient temperature or even 1.6A under certain conditions. Note: This board must be used with the NCV7052XGEVK Automotive Stepper Motor Driver Kit. Features and Applications Features Low bill of materials Small form factor (40mm x 32mm (20mm x 15mm active area)) Plug and Play in combination with NCV7052xGEVK Microstepping (full step, 1/2(compensated and uncompensated), 1/4, 1/8, 1/16, 1/32) Nominal current of 800mA (1.6A under certain conditions) Fully integrated current sensing 6V-30V supply voltage On chip 5V/50mA regulator (Watchdog) reset output Compatible with 5V and 3.3V microcontroller Next step and motion direction input Speed and load-angle output Diagnostics information Thermal warning and thermal shutdown Programmable PWM frequency and slope control Applications Flap control in HVAC systems Headlamp Positioning systems Evaluation Board Information Evaluation Board Status Compliance NV705223R1DBGEVB Active Pb-free Short Description Parts Used Action Daughterboard SPI Stepper Driver with Voltage NCV70522MN003G Regulator , NCV70522MN003R2G (NQFP) Evaluation Board Technical Documents Type Document Title Document ID/Size Rev Eval Board: BOM NV705223R1DBGEVB Bill Of Materials ROHS Compliant NV705223R1DBGEVB_BOM_ROHS.PDF - 0 142.0 KB Eval Board: Gerber NV705223R1DBGEVB_GERBER.ZIP 64.0 KB NV705223R1DBGEVB Gerber Layout Files (Zip Format) 0 Eval Board: Schematic NV705223R1DBGEVB Schematic NV705223R1DBGEVB_SCHEMATIC.PDF - 0 170.0 KB Privacy Policy | Terms of Use | Site Map | Careers | Contact Us | Terms and Conditions | Mobile Portal | Mobile App Copyright (c) 1999-2014 ON Semiconductor Follow Us http://www.onsemi.com/PowerSolutions/evalBoard.do?id=NV705223R1DBGEVB[2/27/2014 2:25:12 PM]
