Function
2
ID
Low: 0.4 V max
• Index output
High: 4.5 V min
3
CD
• Connection for external RC time constant circuit.
4
SS
Low: 0.8 V max
• Start/stop switching input
High: 3.5 V min
This is an active-low input.
5
SL
Low: 1.0 V max
• Speed switching input
High: 3.5 V min
6
CLK
Low: 1.0 V max
• Reference clock input
High:
Use a clock rate of 1 MHz for 300 and 360 rpm
VCC–1.0 V min
speeds.
7
GND
• Ground connection
Connect this pin, pin 14, and the frame to ground.
8
VCC
• Power supply
Provide a well-stabilized power supply so that ripple
and noise do not enter the LB1913 from this pin.
9
Rf
• Used for output current detection.
The output current is converted to a voltage and
detected by connecting a resistor (Rf) between this
pin and VCC. The current limiter operates by
detecting the voltage on this pin.
