ISL22511
Single Push Button Controlled Potentiometer (XDCP™)
Data Sheet
September 9, 2015
FN6678.2
Low Noise, Low Power, 32 Taps, Push
Button Controlled Potentiometer
The Intersil ISL22511 is a three-terminal digitally-controlled
potentiometer (XDCP) implemented by a resistor array
composed of 31 resistive elements and a wiper switching
network. The ISL22511 features a push button control, a
shutdown mode, as well as an industry-leading UTQFN
package.
The push button control has individual PU and PD inputs for
adjusting the wiper. To eliminate redundancy, the wiper
position will automatically increment or decrement if one of
these inputs is held longer than one second.
Forcing both PU and PD low for more than two seconds
activates shutdown mode. Shutdown mode disconnects the
top of the resistor chain and moves the wiper to the lowest
position, minimizing power consumption.
The three terminals accessing the resistor chain naturally
configure the ISL22511 as a voltage divider. A rheostat is
easily formed by floating an end terminal or connecting it to
the wiper.

Shutdown Mode
The ISL22511 enters into Shutdown Mode if both PU and PD
inputs are kept LOW for 2 seconds. In this mode, the
resistors array is totally disconnected from its RH pin and the
wiper is moved to position closest to RL pin, as shown in
Figure 13. Note, that PU and PD inputs must be pulled LOW
within tDB time window of 15ms, see “Shutdown Mode
Timing” on page 7. Otherwise all command will be ignored till
both inputs will be released.
RH
Holding either PU, PD or ASE input LOW for more than
15ms will exit shutdown mode and return wiper to prior
shutdown position. If PU or PD will be held LOW for more
than 250ms, the ISL22511 will start auto-increment or
auto-decrement of wiper position.
RTOTAL with VCC Removed
The end to end resistance of the array will fluctuate once
VCC is removed.
