7 / 48 page  TMC2100 DATASHEET (Rev. 1.07 / 2017-MAY-15) 7 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. CFG3 2 3 DI Configuration input CFG2 3 4 DI Configuration input CFG1 4 5 DI Configuration input CFG0 5 7 DI Configuration input STEP 6 8 DI STEP input DIR 7 9 DI DIR input VCC_IO 8 10 3.3 V to 5 V IO supply voltage for all digital pins. DNC 9, 17 11, 14, 16, 18, 20, 22, 23, 28, 41, 43, 45, 47 Do not connect. Leave open! GNDD 10 12 Digital GND. Connect to GND. 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. Tie to GND when using internal sense resistors. 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). CFG4 18 24 DI Configuration input CFG5 19 25 DI Configuration input ERROR 20 26 DO Diagnostic open drain output: driver error INDEX 21 27 DO Diagnostic open drain output: microstep table position index CFG6_ENN 22 29 DI Enable input (high to disable) and power down configuration AIN_IREF 23 30 AI Analog reference voltage for current scaling or reference current for use of internal sense resistors (optional mode) GNDA 24 32 Analog GND. Tie to GND plane. 5VOUT 25 33 Output of internal 5 V regulator. Attach 2.2 µF to 10µF ceramic capacitor to GNDA near to pin for best performance. VCC 26 34 5V supply input for digital circuitry within chip and charge pump. Attach 470nF capacitor to GND (GND plane). May be supplied by 5VOUT. A 2.2 or 3.3 Ohm resistor is recommended for decoupling noise from 5VOUT. When using an external supply, make sure, that VCC comes up before or in parallel to 5VOUT or VCC_IO, whichever comes up later! CPO 27 35 Charge pump capacitor output. CPI 28 37 Charge pump capacitor input. Tie to CPO using 22 nF 50 V capacitor. VCP 29 38 Charge pump voltage. Tie to VS using 100 nF 16 V capacitor. VSA 30 39 Analog supply voltage for 5V regulator. Normally tied to VS. Provide a 100 nF filtering capacitor. OA2 32 42 Motor coil A output 2 BRA 33 44 Sense resistor connection for coil A. Place sense resistor to GND near pin. Tie to GND when using internal sense resistors. OA1 34 46 Motor coil A output 1 TST_MODE 36 1 DI Test mode input. Tie to GND using short wire. Exposed die pad - - Connect the exposed die pad to a GND plane. Provide as many as possible vias for heat transfer to GND plane. Serves as GND pin for digital circuitry. |
