CAT5111YI-50-T3

CAT5111 100-Tap Digitally Programmable Potentiometer (DPPt) with Buffered Wiper Description The CAT5111 is a single digitally programmable potentiometer (DPPt) designed as an electronic replacement for mechanical potentiometers. Ideal for automated adjustments on high volume production lines, they are also well suited for applications where equipment requiring periodic adjustment is either difficult to access or located in a hazardous or remote environment. The CAT5111 contains a 100−tap series resistor array connected between two terminals RH and RL. An up/down counter and decoder that are controlled by three input pins, determines which tap is connected to the wiper, RWB. The CAT5111 wiper is buffered by an op amp that operates rail to rail. The wiper setting, stored in non−volatile memory, is not lost when the device is powered down and is automatically recalled when power is returned. The wiper can be adjusted to test new system values without effecting the stored setting. Wiper−control of the CAT5111 is accomplished with three input control pins, CS, U/D, and INC. The INC input increments the wiper in the direction which is determined by the logic state of the U/D input. The CS input is used to select the device and also store the wiper position prior to power down. The digitally programmable potentiometer can be used as a buffered voltage divider. For applications where the potentiometer is used as a 2−terminal variable resistor, please refer to the CAT5113. The buffered wiper of the CAT5111 is not compatible with that application.

Electronic Potentiometer Implementation http://onsemi.com 2 CAT5111 Device Operation The CAT5111 operates like a digitally controlled potentiometer with RH and RL equivalent to the high and low terminals and RWB equivalent to the mechanical potentiometer’s wiper. There are 100 available tap positions including the resistor end points, RH and RL. There are 99 resistor elements connected in series between the RH and RL terminals. The wiper terminal is connected to one of the 100 taps and controlled by three inputs, INC, U/D and CS. These inputs control a seven−bit up/down counter whose output is decoded to select the wiper position. The selected wiper position can be stored in nonvolatile memory using the INC and CS inputs. With CS set LOW the CAT5111 is selected and will respond to the U/D and INC inputs. HIGH to LOW transitions on INC will increment or decrement the wiper (depending on the state of the U/D input and seven−bit counter). The wiper, when at either fixed terminal, acts like its mechanical equivalent and does not move beyond the last position. The value of the counter is stored in nonvolatile memory whenever CS transitions HIGH while the INC input is also HIGH. When the CAT5111 is powered−down, the last stored wiper counter position is maintained in the nonvolatile memory. When power is restored, the contents of the memory are recalled and the counter is set to the value stored. With INC set low, the CAT5111 may be de−selected and powered down without storing the current wiper position in nonvolatile memory. This allows the system to always power up to a preset value stored in nonvolatile memory. Pin Description INC: Increment Control Input The INC input (on the falling edge) moves the wiper in the up or down direction determined by the condition of the U/D input. U/D: Up/Down Control Input The U/D input controls the direction of the wiper movement. When in a high state and CS is low, any high−to−low transition on INC will cause the wiper to move one increment toward the RH terminal. When in a low state and CS is low, any high−to−low transition on INC will cause the wiper to move one increment towards the RL terminal. RH: High End Potentiometer Terminal RH is the high end terminal of the potentiometer. It is not required that this terminal be connected to a potential greater than the RL terminal. Voltage applied to the RH terminal cannot exceed the supply voltage, VCC or go below ground, GND. RWB: Wiper Potentiometer Terminal (Buffered) RWB is the buffered wiper terminal of the potentiometer. Its position on the resistor array is controlled by the control inputs, INC, U/D and CS. RL: Low End Potentiometer Terminal RL is the low end terminal of the potentiometer. It is not required that this terminal be connected to a potential less than the RH terminal. Voltage applied to the RL terminal cannot exceed the supply voltage, VCC or go below ground, GND. RL and RH are electrically interchangeable. CS: Chip Select The chip select input is used to activate the control input of the CAT5111 and is active low. When in a high state, activity on the INC and U/D inputs will not affect or change the position of the wiper. http://onsemi.com 3 CAT5111 Table 1.
