Current limiter function control pin
The output current can be modified linearly by the voltage
applied to this pin.
Slope = 0.5A/V typical at Rf = 0.5Ω
Control reference voltage pin
Although this level is set to about 0.3 × V CC internally,
this voltage can be changed by applying an external
voltage with a low-impedance circuit. (The input
impedance is about 3.5kΩ.)
Speed control pin
Control consists of constant current control in which
current feedback is applied from Rf.
Gm = 0.58A/V typical at Rf = 0.5Ω
Integrating amplifier output pin
Integrating amplifier inverting input pin
Integrating amplifier noninverting input pin
Hall sensor signal one-shot multivibrator output pin
This pin must be left open when unused.
Input adjustment pin (for speed control)
This pin must be shorted to ground when unused.
