*1. <Power supply-GND wiring>
SGND is connected to the control circuit power supply system.
*2. <Power stabilization capacitor for regeneration>
For the CM capacitor that is a power stabilization capacitor for PWM drive and for absorption of kick-back, the
capacitance uses 0.1
F or more. In this IC, the lower Transistor performs current regeneration by means of
switching of upper Transistor. Connect CM between VCC and GND with the thick pattern and along the shortest
route.
*3. <Zener diode to stabilize power supply for regneration>
Be sure to use the zener diode if kick-back causes excessive increase of the supply voltage because such increase
damages IC.
*4. <Hall input>
Wiring need to be short to prevent carrying of the noise. If the noise is carried, insert a capacitor between IN+ and
IN-. The Hall input circuit is a comparator having a hysteresis of 20mV. It is recommended that the Hall input level
is more than three times (60mVp-p) this hysteresis.
*5. <Capacitor to set the PWM oscillation frequency>
With CP = 100pF, oscillation occurs at f = 25kHz and provides the basic frequency of PWM.
*6. <RD output>
This is the open collector output, which outputs “L” during rotation and “H” at stop. This output is left open when
not used.
*7. <FG output>
This is the open collector output, which can detect the rotation speed using the FG output according to the phase shift.
This output is left open when not used.
*8. <HB pin>
This is a Hall element bias pin, that is, the constant-voltage output pin.
*9. <RMI pin>
This is the minimum speed setting pin, which is pulled up with 6VREG when not used.
When IC power may possibly be turned OFF first when the pin is used, be sure to insert a current limiting resistor to
prevent inflow of the large current. (The same applies to the VTH pin.)
*10. <ROFF pin>
This pin sets the soft switching time to cut the reactive current before phase change and is connected to 6VREG
when not used.
*11. <VLIM pin>
This pin activates the current limiter when the SENSE pin voltage is higher than the VLIM pin voltage and is
connected to 6VREG when not used.
*12. <SENSE pin>
This is connected to GND when not used.
*13. <VOVER pin>
This is a pin for constant-voltage bias and should be used for application of 24V and 48V. (Refer to the sample
application circuit.) Be sure to use the current limiting resistor. This is left open when not used.
