April 2015 Edition / document number 1094861_PDF_E - 05 / subject to change
5.1.3 «Enable»
The «Enable» input enables or disables the power stage.
If a voltage higher than 2.4 V is applied to the «Enable» input, the amplifier is
activated (Enable). A speed ramp will be performed during acceleration.
Enable
Input voltage > 2.4 V
Motor shaft running
If the input is not connected (floating) or ground potential is applied to the
«Enable» input, the power stage is high impedant and the motor shaft free-
wheels and slows down (Disable).
Disable
Input not connected (floating)
Input set to Gnd
Input voltage < 0.8 V
Power stage switched off
The «Enable» input is protected against overvoltage.
Enable
Pin number [22] «Enable»
Input voltage range
0 ... +5 V
Input impedance
100 k
Ω
(in range 0 ... +5 V)
Continuous overvoltage protection
-55 ... +55 V
Delay time
max. 40 ms
5.1.4 «Direction»
The «Direction» input determines the rotational direction of the motor shaft.
When the level changes, the motor shaft slows down with a ramp to standstill,
and accelerates with a speed ramp in the opposite direction, until the target
speed is reached again.
If the input is not connected (floating) or ground potential is applied to the
«Direction» input, the motor shaft runs clockwise (CW).
CW
Input not connected (floating)
Input set to Gnd
Input voltage < 0.8 V
Clockwise (CW)
If a voltage higher than 2.4 V is applied to the «Direction» input, the motor
shaft runs counter-clockwise (CCW).
CCW
Input voltage > 2.4 V
Counter-clockwise (CCW)
The «Direction» input is protected against overvoltage.
