The connection of the bus interface and further digital signals is left out for clarity. 3.1 Standard Application Circuit VCC_IO TMC5041 SPI interface CSN SCK SDO SDI reference switch processing reference switch processing Controller 2 5V Voltage regulator charge pump 22n CLK_IN +VIO INT PP INT & position pulse output opt. ext. clock 12-16MHz 3.3V or 5V I/O voltage 100n Controller 1 Full Bridge A Full Bridge B +VM VS stepper motor #1 N S O1A1 O1A2 BR1A O1B1 O1B2 Driver 1 100n BR1B Full Bridge A Full Bridge B stepper motor #2 N S O2A1 O2A2 BR2A O2B1 O2B2 Driver 2 BR2B VS 100n 100µF VCP 100n +VM 5VOUT VSA 4.7µ VCC 100n Optional use lower voltage down to 6V 2R2 470n Figure 3.1 Standard application circuit The standard application circuit uses a minimum set of additional components in order to operate the motor. Use low ESR capacitors for filtering the power supply which are capable to cope with the current ripple. The current ripple often depends on the power supply and cable length. The VCC_IO voltage can be supplied from 5VOUT, or from an external source, e.g. a low drop 3.3V regulator. In order to minimize linear voltage regulator power dissipation of the internal 5V voltage regulator in applications where VM is high, a different (lower) supply voltage can be used for VSA, if available. For example, many applications provide a 12V supply in addition to a higher supply voltage like 24V. Using the 12V supply for VSA will reduce the power dissipation of the internal 5V regulator to about 37% of the dissipation caused by supply with the full motor voltage. For best motor chopper performance, an optional R/C-filter de-couples 5VOUT from digital noise cause by power drawn from VCC. Basic layout hints Place sense resistors and all filter capacitors as close as possible to the related IC pins. Use a solid common GND for all GND connections, also for sense resistor GND. Connect 5VOUT filtering capacitor directly to 5VOUT and GNDA pin. See layout hints for more details. Low ESR electrolytic capacitors are recommended for VS filtering. Attention In case VSA is supplied by a different voltage source, make sure that VSA does not exceed VS by more than one diode drop upon power up or power down. |
