2 Introduction
The controller is designed for an input voltage range from 6.5V to 24V.
This means that the controller works with the 6 cell NC packs commonly
used in the RC car sector, but also with lead batteries up to 24V. Two stan-
dard automotive fuses protect the model and the battery from excessive
currents.
The controller has a built-in BEC circuit to power the receiver from the drive
battery.
Please note that the removable BEC current decreases as the supply voltage
increases.
To disconnect the internal BEC regulator from the receiver supply, a jumper
must be removed.
As a failsafe function, an extensive plausibility check of the transmitter
signals is integrated in the software.
In addition, the controller has a temperature monitoring of the output
stage.
It switches off at 75°C and can be switched on again at 65°C and above.
To do this, the transmitter sticks must be set to the neutral position to
prevent a sudden start after the controller has cooled down.
2.1 Technology
The controller is microprocessor controlled. The processor works with
16MHz clock frequency.
The output stage is constructed from N-channel MOSFETs, which have an
inrush resistance of only 0.008 ohms and a continuous current capability of
60A. To make effective use of the low internal resistance, the output stage
transistors are driven by sophisticated MOSFET push-pull output stages
with integrated charge pump.
Under normal ambient conditions, a continuous current of 10A is achieved.
The controller operates with a PWM frequency of 16kHz.
