4.4 Voltage range

4.4.1 Programmer Output / Supply Voltage range

The PPM3 Module has been designed so that it can be powered from an external 9.0 to 12.0V DC
regulated power supply via the jack socket (J6) or directly from a Target System running at +5.0V DC.
The programmer is capable of generating a controlled supply voltage to the Target System of
between 3.0V and 5.0V at 300mA, but this is only possible if the programmer is powered from an
external 9.0 to 12.0V power supply,

# Programmer mode
1 Programmer powering the Target System
•
Programmer must be powered by external 9V DC supply via DC
power connector (J6) or Molex power connector (J16)
•
Programmer is capable of generating a controlled supply
voltage to the Target System of between 3.0V and 5.0V at
300mA
•
Target Sense functionality is only available in this mode.
2 Target System powering the programmer
•
Programmer circuitry must be powered at +5V
•
Target System must supply +5.0V via one of the ISP Headers to
the programmer.
