EVAL6207Q STMicroelectronics

EVAL6207Q Dual full bridge with integrated PWM current controllers Data brief Description The EVAL6207Q is a dual full bridge driver board allowing the user to test the L6207Q functions. The dual full bridges integrated into the L6207Q can be used to drive a single two phase stepper motor or up to four DC motors (unidirectional). The device also includes two independent constant OFF time PWM current controllers. The board can be driven using the STEVAL- PCC009V2 communication board and the TM PractiSPIN 2 evaluation software. Features Voltage range from 8 V to 52 V Phase current up to 2.5 A r.m.s. Adjustable constant t PWM current control OFF Logic inputs 5 V / 3.3 V compliant Small application footprint with high thermal performance Suitable to be used in combination with TM PractiSPIN 2 software August 2013 DocID025098 Rev 1 1/10 For further information contact your local STMicroelectronics sales office. www.st.comBoard description EVAL6207Q 1 Board description .
