EV6501AGF-00B 2.5A, 35V Bipolar Stepper Motor Driver Evaluation Kit The Future of Analog IC Technology DESCRIPTION FEATURES The MP6501AGF demo board is a customized evaluation board for a stepper motor driver with a built-in micro-stepping translator. The MP6501AGF demo board operates from a supply voltage of up to 35V and delivers motor current up to 2.5A. It operates a bipolar stepper motor in full-, half-, quarter-, eighth-, and sixteenth- step modes by setting the MS3, MS2, and MS1. The input control signals and reference voltage are applied through the connector or generated on the board.

All Rights Reserved. 6 EV6501A – EVB DESCRIPTION QUICK START GUIDE The power and control signals for the EV6501AGF-00B are applied through the terminal block TS2 or the header connector P3. Each pin in the connector is labeled on the EVB. The supplied voltage should be between 8V and 35V (12V or 24V nominal in most cases). The stepper motor is connected to terminal block TS1 or connector P2. Each pin is labeled. Controlling the MP6501A using the On-Board USB Microcontroller and PCB GUI Program: 1. Place a jumper on JP3, nENCTRL. 2. Set all of the switches on the DIP switch SW1 to “off.” 3. To use the DIP switch or to drive signals externally to the test points, remove the jumper from JP3. 4. To use a fixed off time, set by R17 (196k), place a jumper across the pins labeled “FIX” on header JP2. 5. To use the trim pot to adjust the off time, place the jumper on the pins labeled “ADJ.” SW3 selects either an internally generated STEP signal or an externally generated STEP signal. SW4 selects either a fixed voltage for the VREF input or the on-board DAC, which is set by the GUI. SW5 selects either a fixed voltage for the MDS input or the on-board DAC, which is set by the GUI. SW6 selects between a 3.3V voltage for the pull-up resistors or an externally supplied voltage. . The LED D5 indicates the status of FAULT. When over-temperature protection or over-current protection occurs, nFAULT is pulled down to a low level and lights up the LED. R18 and R19 are the current-sense resistors connected directly to SENA and SENB, respectively. The other sides of these resistors are connected to GND. The resistors, in conjunction with the voltage applied to VREF, control the current through the MP6501A. EV6501A Rev.1.0 3/9/2015 www.MonolithicPower.com MPS Proprietary Information.

All Rights Reserved. 7 EV6501A – EVB DESCRIPTION GUI OPERATION A PC based GUI program is used to control the EV6501AGF-00B from a Windows PC. Connect the board to a USB port on the computer. When launched, the GUI shows selection buttons for three pages as shown below: When the “Monitor” button is clicked, the screen below is displayed: From this screen, a reset pulse can be generated for the MP6501A by pressing “Reset.” You can enter or exit sleep mode by pressing “Sleep.” Pressing “Enable” will enable or disable the MP6501A. *Note that the MP6501A must be enabled before trying to move the motor using the next screen.

All Rights Reserved. 8 EV6501A – EVB DESCRIPTION If a fault condition (over temperature, over current, etc.) is encountered, the “Fault” button will illuminate. When the “Basic Input” button is clicked, the screen below is displayed: Step mode (from 1/16-step to full-step) and the step direction are selectable. Entering a numeric value in the “Peak Current” box sets the peak winding current (the value assumes a 100mΩ sense resistor, which is normally installed on the EVB). Decay mode can be selected. Select automatic decay mode or enter a numeric value for the fast decay portion of mixed decay (for slow decay enter “1,” for fast decay, enter “100”). The “Speed Control” section allows you to set a number of steps for ramp up and ramp down, a number of steps to run at the target step rate, and the frequency (step rate) in Hz or PPS. The resulting rampup, run, and ramp-down times are displayed. Once these parameters are set, press the “Program” button and the motor will move as programmed.
