Output Enable
Reference Output
The Forward/Reverse Input is used to change the direction of motor rotation.
These three Sensor Inputs control the commutation sequence.
A logic high at this input causes the motor to run, while a low causes it to coast.
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.

Current Sense Noninverting Input
A 100 mV signal, with respect to Pin 15, 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.
The Oscillator frequency is programmed by the values selected for the timing
components, R
T
and C
T
.
This input is normally connected to the speed set potentiometer.
This input is normally connected to the Error Amp Output in open loop
applications.

Fault Output
This pin is available for compensation in closed loop applications.
This open collector output is active low during one or more of the following
conditions: Invalid Sensor Input code, Enable Input at logic 0, Current Sense
Input greater than 100 mV (Pin 9 with respect to Pin 15), Undervoltage Lockout
activation, and Thermal Shutdown.
Reference pin for internal 100 mV threshold. This pin is normally connected to
the bottom side of the current sense resistor.

This pin supplies a ground for the control circuit and should be referenced back
to the power source ground.

V
CC
This pin is the positive supply of the control IC. The controller is functional over a
minimum V
CC
range of 10 to 30 V.
The high state (V
) of the Bottom Drive Outputs is set by the voltage applied to
this pin. The controller is operational over a minimum V
C
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.

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.
A logic low state at this input allows the motor to run, while a high state does not
allow motor operation and if operating causes rapid deceleration.
