47 Potentiometers with cut track The cut track is an area with very high resistive value, resulting in an open circuit. It is widely used in lighting applications. Mechanical life with cut track needs to be confirmed. PCI = Cut at initial position, when the potentiometer is turned fully counter clockwise. PCF = Cut at final position, when the potentiometer is turned fully clockwise. Other positions are available on request. PCI PCF CA9 CE9 A B C A B C A B C A B C Potentiometers with detents ACP s patented detent (DT) feature is especially suitable for control applications where the end used will turn a knob inserted in the potentiometer. Detents can be used to add a click feeling to the turning of the potentiometer or to control the position in which the wiper is placed, assuring a particular output value with a narrow tolerance. Detents can be light or strong, or even a combination of different feelings. They can be evenly distributed along the angle (standard) or tailored to match customers request. They can also be combined with special tapers: constant value areas, open circuit zone, different slopes, etc. One common example is a potentiometer with detents and matching non-overlapping voltage values in specific angular positions, used to feed in a voltage value to a microprocessor: Example of DT with control of value in each DT.

For potentiometers with detents, mechanical life is also.000 cycles if no additional cycles are mentioned. Please, indicate the number of cycles needed with LV (number of cycles), for example: LV07, for cycles.

Drivers are enabled in pairs, with drivers and enabled by,en and drivers and enabled by,en. When an enable input is high, the associated drivers are enabled and their outputs are active and in phase with their inputs. When the enable input is low, those drivers are disabled and their outputs are off and in the high-impedance state. With the proper data inputs, each pair of drivers forms a full-h (or bridge) reversible drive suitable for solenoid or motor applications.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES:. All voltage values are with respect to the network ground terminal.. For operation above C free-air temperature, derate linearly at the rate of 6.6 mw/ C.. For operation above C case temperature, derate linearly at the rate of 7. mw/ C. Due to variations in individual device electrical characteristics and thermal resistance, the built-in thermal overload protection may be activated at power levels slightly above or below the rated dissipation.

Bipolar Stepping-Motor Control mounting instructions The Rthj-amp of the L9 can be reduced by soldering the pins to a suitable copper area of the printed circuit board or to an external heatsink. Figure 9 shows the maximum package power P TOT and the θ JA as a function of the side of two equal square copper areas having a thickness of µm (see Figure 7). In addition, an external heat sink can be used (see Figure 8). During soldering, the pin temperature must not exceed 60 C, and the soldering time must not be longer than seconds. The external heatsink or printed circuit copper area must be connected to electrical ground. POST OFFICE BOX 60 DALLAS, TEXAS 76
