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.
