FAQs
Q: What output voltage is provided by the TSWITX-G4-EVM system?
A: Output voltage is receiver dependant. For the TSWIRX-5V2-EVM, the output is 5 volts.
Q: Is the TSWITX-G4-EVM compliant with Qi or another wireless transmission standard?
A: These low power wearable solutions are not based on existing standards in order to employ smaller
coils and other optimizations that better suit the low power system environment.
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 = Receive
Mid-section = Device Voltage or Wattage
Suffix = Equipment type:
EVM = Evaluation Module
MOD = Production Module
Thus, the TSWITX-G4-EVM is a Wearable Infrastructure, Transmitter Evaluation Module provided by
Semtech.
Q: Does the TSWITX-G4-EVM implement Foreign Object Detection (FOD)?
A: FOD detection is an important protection in higher power systems, but in low power wearable
infrastructure systems there is no risk of overheating, rendering FOD management unnecessary.
Q: What if my questions weren’t answered here?
