PIN FUNCTION DESCRIPTION
These three open collector Top Drive Outputs are designed to drive the external upper
power switch transistors.
The Forward/Reverse Input is used to change the direction of motor rotation.
These three Sensor Inputs control the commutation sequence.
This output provides charging current for the oscillator timing capacitor C
reference for the Error Amplifier. It may also serve to furnish sensor power.
The Oscillator frequency is programmed by the values selected for the timing
components, R
This input is normally connected to the speed set potentiometer.
This input is normally connected to the Error Amp Output in open loop applications.
This pin is available for compensation in closed loop applications.
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.
This pin supplies a separate ground return for the control circuit and should be
referenced back to the power source ground.
This pin is the positive supply of the control IC. The controller is functional over a V
range of 10 to 30 V.
These three totem pole Bottom Drive Outputs are designed for direct drive of the
external bottom power switch transistors.
The electrical state of this pin configures the control circuit operation for either 60°
(high state) or 120° (low state) sensor electrical phasing inputs.
A logic high at this input causes the motor to run, while a low causes it to coast.
