Jumper

Name

Function

U, V, W

X105,
X106,
X107

At these jumpers you can measure phase currents and voltages of the
BLDC motor.

Filt1, Filt2, Filt3

X108,
X109,
X110

The microcontroller includes an Analog-to-Digital Converter (ADC) with
eight analog input channels. The input signals of the ADC channels 5, 6
and 7 are selectable. You have two options:

1. filtered coil voltages provided by the TMC603

(jumpers plugged in pin 1 and pin 2)

2. unfiltered coil voltages provided by a resistor divider

(jumpers plugged in pin 2 and pin 3)

The default option are the filtered coil voltages provided by the TMC603.

F1, F2, F3

X207,
X208,
X209

Here you can measure the filtered voltages Filt1, Filt2 and Filt3 of the coils
directly provided by the TMC603.

HALL1, HALL2,
HALL3

X212,
X213,
X214

You must plug these jumpers to use the TMC603 evaluation board with
the BLDC back EMF commutation hallFX™. Unplug these jumpers to use
the hall sensors.

MESS_IM3

X114

The input signal of the ADC channel 3 is also selectable. You have two
options:

1. current measurement output CUR3 of the TMC603

(jumper plugged in pin 1 and pin 2)

2. shunt based current measurement with a difference amplifier

(jumper plugged in pin 2 and pin 3)

The  default  option  is  the  current  measurement  output  CUR3  of  the
TMC603.  Please  note  that  the  current  measurement  outputs  CUR1  and
CUR2 are connected directly to the ADC channels 0 and 1.

M.IM1, M.IM2,
M.IM3

X204,
X205,
X206

Here you can measure the currents CUR1, CUR2 and CUR3 of the coils
directly provided by the TMC603.

Test Output

X203

The test output is reserved for manufacturing test. Please refer the
TMC603 data sheet for more details.

ERROUT

X215

Here you can measure the error output signal of the TMC603. The
TMC603 has three different sources for signaling an error:

1. Undervoltage of the low side supply

2. Undervoltage of the charge pump

3. Short to GND detector

Upon any of these events the error output is pulled low.

Bridge Shunt

X302,
X303

You  must  plug  these  jumpers  to  bypass  the  low  end  resistor.  You  can
unplug  these  jumpers  for  other  applications  like  a  shunt  based  current
measurement  with  a  difference  amplifier.  The  default  option  is  to bypass
the low end resistor.
