Pin function
When this pin is at 0.7V or
less or when it is open, only
the FG/PG amplifier operates.
In the motor drive state, the
pin should be at 2V or higher.
CSLP pin charge/discharge
current switching pin.
Setting this pin to 2V or higher
switches the triangular wave
slope that determines soft
switching.
Motor forward/reverse
switching pin.
Low: reverse
(–0.2V to +0.7V or open)
High: forward
(2V to V

voltage.
Power supply pin for supplying
source side predriver voltage
and coil waveform detect
comparator voltage.
Power supply pin for circuits
except motor voltage, source
side predriver voltage, and coil
waveform detect comparator
voltage.
Pins for connecting triangular
wave oscillator capacitor. This
triangular wave coil output
performs waveform soft
switching.
