Power and Communication Connector 

A  6pin  JST  PH-series  2mm  pitch  single  row  connector  is  used  for  power  supply,  RS485  and  CAN  serial 
communication. Please note the additional power supply information in chapter 4.3.1.1. 
 

Note: CAN interface will be de-activated in case USB is connected due to internal sharing of hardware 
resources.

Power Supply 

 

For proper operation care has to be taken with regard to power supply concept and design. Due to space 
restrictions  the  TMCM-1140  includes  about  40µF/35V  of  supply  filter  capacitors.  These  are  ceramic 
capacitors  which have been selected for  high  reliability and long life time.  The  module includes  a 28V 
suppressor  diode  for  over-voltage  protection.  There  is  no  reverse  polarity  protection.  The  module  will 
short any reversed supply voltage due to the suppressor diode (uni-directional version) and the internal 
diodes of the driver transistors.  
 
It  is  important  that  the  power  supply  voltage  is  kept  below  the  upper  limit  of  28V  (please  see  also 
chapter  6,  operating  values).  Otherwise  the  driver  electronics  might  be  seriously  damaged!  Especially, 
when  the  selected  operating  voltage  is  near  the  upper  limit  a  regulated  power  supply  is  highly 
recommended. 
 

It is recommended to connect an electrolytic capacitor of significant size (e.g. 470µF/35V) to the power 
supply lines next to the PD42-1140! 

 
In addition to power stabilization (buffer) and filtering this added capacitor will also reduce any voltage 
spikes which might otherwise occur from a combination of high inductance power supply wires and the 
ceramic capacitors. In addition it will limit slew-rate of power supply voltage at the module. The low ESR 
of ceramic-only filter capacitors may cause stability problems with some switching power supplies.
