One-chip motor driver
7.12 Oscillator
The RC oscillator uses two external components (R
REF
and C
OSC
) to fix its frequency at
18 MHz. R
REF
is used to generate a reference current. This reference current is used to
charge and discharge C
OSC
. The nominal oscillation frequency f
osc
is 18 MHz with
R
REF
= 47 k
(2 % tolerance) and C
OSC
= 70 pF (5 % tolerance). These values are fixed.
The oscillator can be overruled by applying an 18 MHz clock to pin COSC. The reference
current derived from R
REF
is also used for R
LIM
and R
EMF
. R
REF
should always be
connected.
7.13 Muting functions
Pins CTL1 and CTL2 are used to mute certain parts of the IC. See
Table 3
