11 / 103 page  TMC2130 DATASHEET (Rev. 1.09 / 2017-MAY-15) 11 www.trinamic.com 2.2 Signal Descriptions Pin QFN36 TQFP48 Type Function CLK 1 2 DI CLK input. Tie to GND using short wire for internal clock or supply external clock. CSN_CFG3 2 3 DI (tpu) SPI chip select input (negative active) (SPI_MODE=1) or Configuration input (SPI_MODE=0) (tristate detection). SCK_CFG2 3 4 DI (tpu) SPI serial clock input (SPI_MODE=1) or Configuration input (SPI_MODE=0) (tristate detection). SDI_CFG1 4 5 DI (tpu) SPI data input (SPI_MODE=1) or Configuration input (SPI_MODE=0) (tristate detection). SDO_CFG0 5 7 DIO (tpu) SPI data output (tristate) (SPI_MODE=1) or Configuration input (SPI_MODE=0) (tristate detection). STEP 6 8 DI STEP input DIR 7 9 DI DIR input VCC_IO 8 10 3.3V to 5V IO supply voltage for all digital pins. DNC 9 11, 14, 16, 18, 20, 22, 28, 41, 43, 45, 47 - Do not connect. Leave open to ensure highest distance for high voltage pins in TQFP package! Pins 9 and 11 may be connected to GND or left open. SPI_MODE 10 12 DI (pu) Mode selection input with pullup resistor. When tied low, the chip is in standalone mode and pins have their CFG functions. When tied high, the SPI interface is available for control. Integrated pull-up resistor. N.C. 11 6, 31, 36 Unused pin, connect to GND for compatibility to future versions. GNDP 12, 35 13, 48 Power GND. Connect to GND plane near pin. OB1 13 15 Motor coil B output 1 BRB 14 17 Sense resistor connection for coil B. Place sense resistor to GND near pin. An additional 100nF capacitor to GND (GND plane) is recommended for best performance. OB2 15 19 Motor coil B output 2 VS 16, 31 21, 40 Motor supply voltage. Provide filtering capacity near pin with short loop to nearest GNDP pin (respectively via GND plane). DCO 17 23 DIO dcStep ready output DCEN_CFG4 18 24 DI (tpu) dcStep enable input (SPI_MODE=1) - tie to GND for normal operation (no dcStep) or Configuration input (SPI_MODE=0) (tristate detection). DCIN_CFG5 19 25 DI (tpu) dcStep gating input for axis synchronization (SPI_MODE=1) or Configuration input (SPI_MODE=0) (tristate detection). DIAG0 20 26 DIO Diagnostics output DIAG0. Use external pull-up resistor with 47k or less in open drain mode. DIAG1 21 27 DIO Diagnostics output DIAG1. Use external pull-up resistor with 47k or less in open drain mode. DRV_ENN_ CFG6 22 29 DI (tpu) Enable input (SPI_MODE=1) or configuration / Enable input (SPI_MODE=0) (tristate detection). The power stage becomes switched off (all motor outputs floating) when this pin becomes driven to a high level. AIN_IREF 23 30 AI Analog reference voltage for current scaling (optional mode) or reference current for use of internal sense resistors |
