TRINAMIC Motion Control GmbH · Motor Driver ICs · PQFP-44(10x10)

TMC260C-PA-T from TRINAMIC Motion Control GmbH, in a PQFP-44(10x10). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 n.c. unconnected No internal connection; can be tied to any net, e.g. to improve power routing to pins VSA and VSB.
2 OA1 output Bridge A1 output (VS domain); interconnect with pins 3, 7, 8 using thick traces capable of carrying the motor current and distributing heat into the PCB.
3 OA1 output Bridge A1 output (VS domain); interconnect with pins 2, 7, 8 using thick traces capable of carrying the motor current and distributing heat into the PCB.
4 VSA power_in Bridge A positive power supply; connect to VS and provide sufficient filtering capacity for chopper current ripple.
5 OA2 output Bridge A2 output (VS domain); interconnect with pins 6, 10, 11 using thick traces capable of carrying the motor current and distributing heat into the PCB.
6 OA2 output Bridge A2 output (VS domain); interconnect with pins 5, 10, 11 using thick traces capable of carrying the motor current and distributing heat into the PCB.
7 OA1 output Bridge A1 output (VS domain); interconnect with pins 2, 3, 8 using thick traces capable of carrying the motor current and distributing heat into the PCB.
8 OA1 output Bridge A1 output (VS domain); interconnect with pins 2, 3, 7 using thick traces capable of carrying the motor current and distributing heat into the PCB.
9 BRA passive Bridge A negative power supply via sense resistor in bridge foot point (analog input).
10 OA2 output Bridge A2 output (VS domain); interconnect with pins 5, 6, 11 using thick traces capable of carrying the motor current and distributing heat into the PCB.
11 OA2 output Bridge A2 output (VS domain); interconnect with pins 5, 6, 10 using thick traces capable of carrying the motor current and distributing heat into the PCB.
12 SRA input Sense resistor input A for chopper current regulation (analog input).
13 5VOUT power_out Output of the on-chip 5V linear regulator supplying the low-side MOSFETs and internal analog circuitry; requires an external capacitor to GND close to the pin (470nF ceramic is sufficient).
14 SDO output SPI serial data output, referenced to VCC_IO.
15 SDI input SPI serial data input, referenced to VCC_IO (scan test input in test mode).
16 SCK input Serial clock input of the SPI interface, referenced to VCC_IO (scan test shift enable input in test mode).
17 GND power_in Digital and analog low power GND.
18 CSN input Chip select input for the SPI interface, active low, referenced to VCC_IO.
19 ENN input Power MOSFET enable input, active low; all MOSFETs are switched off when disabled.
20 n.c. unconnected No internal connection.
21 CLK input System clock input for all internal operations; tie low to use the on-chip oscillator, a high signal disables the on-chip oscillator until power down.
22 SRB input Sense resistor input B for chopper current regulation (analog input).
23 OB2 output Bridge B2 output (VS domain); interconnect with pins 24, 28, 29 using thick traces capable of carrying the motor current and distributing heat into the PCB.

26 OB1 output Bridge B1 output (VS domain); interconnect with pins 27, 31, 32 using thick traces capable of carrying the motor current and distributing heat into the PCB.
27 OB1 output Bridge B1 output (VS domain); interconnect with pins 26, 31, 32 using thick traces capable of carrying the motor current and distributing heat into the PCB.
28 OB2 output Bridge B2 output (VS domain); interconnect with pins 23, 24, 29 using thick traces capable of carrying the motor current and distributing heat into the PCB.
29 OB2 output Bridge B2 output (VS domain); interconnect with pins 23, 24, 28 using thick traces capable of carrying the motor current and distributing heat into the PCB.
30 VSB power_in Bridge B positive power supply; connect to VS and provide sufficient filtering capacity for chopper current ripple.
31 OB1 output Bridge B1 output (VS domain); interconnect with pins 26, 27, 32 using thick traces capable of carrying the motor current and distributing heat into the PCB.
32 OB1 output Bridge B1 output (VS domain); interconnect with pins 26, 27, 31 using thick traces capable of carrying the motor current and distributing heat into the PCB.
33 n.c. unconnected No internal connection; can be tied to any net, e.g. to improve power routing to pins VSA and VSB.
34 n.c. unconnected No internal connection.
35 VHS power_in High-side supply voltage (motor supply voltage - 10V).
36 VS power_in Motor supply voltage.
37 TST_ANA unconnected Reserved analog output; do not connect.
38 SG_TST output stallGuard2 output that signals a motor stall, active high, referenced to VCC_IO.
39 GND power_in Digital and analog low power GND.
40 VCC_IO power_in Input/output supply voltage VIO for all digital pins; tie to digital logic supply, operation allowed in 3.3V and 5V systems.
41 DIR input Direction input sampled on an active STEP edge (low increases, high decreases the microstep counter), with 60-ns internal glitch filter.
42 STEP input Step input with active edges rising or both rising and falling per the DEDGE mode bit, with 60-ns internal glitch filter.
43 TST_MODE input Test mode input that puts the IC into test mode; tie to GND for normal operation.
44 GND power_in Digital and analog low power GND.
