System architecture
SX8120/21 architecture
The system is based on an integrated 5% precise counter. It starts and stops pulses based on the command of
a button and times-out after a selectable period of time.

Figure 2. SX8120/21 Architecture
The MOTOR output polarity is controlled by the POLARITY input. If POLARITY is connected the VDD that the
MOTOR will be active high, if POLARITY is connected the VSS, the MOTOR will be active low. MOTOR output is
usually followed by an NPN transistor to drive the motor, in this case it is active high.
In parallel with the motor there is a LED output that sends 3 us pulses at 43 kHz that can be used to drive a
white or green LED with an NPN transistor and a 40-200 uH coil.
