Functions
OUT 1: Hall element input pins for Phase 1. ‘‘H’’ logic is the state when IN+ > IN.
OUT 2: Hall element input pins for Phase 2. ‘‘H’’ logic is the state when IN+ > IN.
OUT 3: Hall element input pins for Phase 3. ‘‘H’’ logic is the state when IN+ > IN.
Output pin 1.
Output pin 2.
Output pin 3.
Power supply for other than output blocks.
Power supply for output blocks.
Output current detection pin. Rf is connected across this pin and GND to detect the output current as
voltage.
Ground for other than output blocks.
The lowest potential of output transistor is the voltage at Rf pin.
Sets the oscillating frequency of the switching regulator.
Outputs duty-controlled pulses.
Open-collector output.
Integrator output pin (speed control pin).
Varies the switching regulator output voltage.
Integrator input pin.
Speed discriminator output pin.
Goes LOW when the specified speed is exceeded.
Suppresses ripples in the motor current during operation of current limiter 2.
Lock detection pin.
Goes HIGH when the motor rotation speed is within the locking range.
FG pulse input (Start/Stop control) pin.
FG pulse input (4 V supply) pin.
FG amp output pin.
Crystal oscillator connecting pin.
5 V supply pin.
No.3302-5/7
