These three Sensor Inputs control the commutation sequence.
7
Reference Output
This output provides charging current for the oscillator timing capacitor C
T
and a
reference for the Error Amplifier. It may also serve to furnish sensor power.
8
Oscillator
The Oscillator frequency is programmed by the values selected for the timing
components, R
T
and C
T
.
9
Error Amp Noninverting Input
This input is normally connected to the speed set potentiometer.
10
Error Amp Inverting Input
This input is normally connected to the Error Amp Output in open loop applications.
11
Error Amp Out/PWM Input
This pin is available for compensation in closed loop applications.
12
Current Sense Noninverting Input
A 100 mV signal, with respect to Pin 13, at this input terminates output switch
conduction during a given oscillator cycle. This pin normally connects to the top side
of the current sense resistor.
13
Gnd
This pin supplies a separate ground return for the control circuit and should be
referenced back to the power source ground.
14
V
CC
This pin is the positive supply of the control IC. The controller is functional over a V
CC
range of 10 to 30 V.

Select
The electrical state of this pin configures the control circuit operation for either 60
°
(high state) or 120
°
(low state) sensor electrical phasing inputs.
19
Output Enable
A logic high at this input causes the motor to run, while a low causes it to coast.
