EVAL6472PD STMicroelectronics

EVAL6472PD Fully integrated stepper motor driver mounting the L6472 in a high power PowerSO package Data brief Description The EVAL6472PD demonstration board is a fully integrated microstepping motor driver. In combination with the STEVAL-PCC009V2 communication board and the SPIN evaluation software, the board allows the user to investigate all the features of the L6472 device. In particular, the board can be used to regulate the L6472 parameters in order to fit application requirements. The 4-layer layout and the PowerSo package allow the top thermal performance to be obtained. The EVAL6472PD supports the daisy chain configuration making it suitable for the evaluation EVAL6472PD of the L6472 in the multi motor applications. Features Voltage range from 8 V to 45 V Phase current up to 3 A r.m.s. Dual SPI connector (with daisy chain configuration suitable) SW input FLAG and BUSY LED indicators High thermal performance (R 12 C/W thj-a typical) Suitable for use in combination with the STEVAL-PCC009V2 March 2015 DocID023463 Rev 2 1/11 For further information contact your local STMicroelectronics sales office. www.st.comBoard description EVAL6472PD Board description Table 1.
