FAQs 

Q: What output voltage is provided by the TSDMRX-5W-EVM system?  

A: 5 volts, at up to 5 watts total power. The TSDMRX-9V/15W-EVM would provide up to 15W at 9V. 

 

Q: What mode does the TSDMRX-5W-EVM operate in?  

A: Qi is the default. With PMA-3 and PMA-8 transmitter types, PMA mode is selected. 

 

Q:  Where can I find more information on the Qi and PMA standards? 

A:  There  are  a  number  of  websites  that  address  this  subject.  A  good  starting  point  for  Qi  would  be: 
http://www.wirelesspowerconsortium.com/technology/how-it-works.html.   
PMA,  which  is  now  joined  with  A4WP,  is  now  called  AirFuel.  Information  on  them  can  be  found  at  the 
following website: http://www.airfuel.org/technologies/inductive. 

 

Q:  Does the EVM part number represent something in particular? 

A: Yes. The part number is broken into a prefix, main body, and suffix, separated by dashes. The prefix is 
comprised of three two letter groupings that each help define the product represented. As such, the part 
number can be read as follows: 

Prefix characters:

1+2 = Company : 

TS = Triune/Semtech

3+4 = Environment : 

DM = Dual Mode

WI = Wearable Infrastructure

5+6 = Type : 

TX = Transmit

RX = Receiver

Mid-section = Device Voltage and/or Wattage. 

Suffix = Equipment type:

EVM = Evaluation Module

MOD = Production Module

 

Therefore,  the  TSDMRX–5W–EVM  is  a  Dual  Mode,  5  Watt  Receiver  Evaluation  Module  provided  by 
Semtech. 

 

Q: What if my questions weren’t answered here? 

A:  Go  to  the  Semtech  website  as  described  on  the  next  page.  An  updated  FAQ  for  the  TSDMRX-5W-
EVM  is  maintained  there  and  may  contain  the  answers  you’re  looking  for.  Your  local  Semtech  FAE  can 
also assist in answering your questions.
