FG function at SPINDLE DRIVE
The FG terminal outputs the square pulse signal synchronizing with the Hall inputs [Hv+, Hv-] timing.
And, the FG terminal is open-collector output.
Phase delay circuit at SLIDE
Phase delay circuit is built in the IC to detect an output spike current, when the motor current direction
is switching.
In switching the motor current direction, Phase delay circuit switch-off all output trangister of H-bridge
for 3μsec.
Output current setting at SLIDE
In this IC, since output tranjister is NPN-type tranjister, motor coil current (Io) is larger than sensing
resistance current about 20mA (TYP.) according to base current of output tranjister.
Therefore please design output current with consisting these base current.
The relationship between hall-amplifier-input and output-current-commutation at SPINDLE DRIVE
The relationship between the hall elements and the motor output current is shown in bellow Figure.
PWM carrier frequency setting
PWM carrier frequency is decided by charging and discharging the capacitor that is connected to OSC terminal
outer IC. Examination of the relationship the capacitor connected to OSC terminal and PWM carrier frequency
is given in following table.
