The Intersil ISL22512 is a three-terminal digitally-controlled
potentiometer (XDCP) implemented by a resistor array
composed of 15 resistive elements and a wiper switching
network. The ISL22512 features a push button control, a
shutdown mode, as well as an industry-leading µTQFN
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 ISL22512 as a voltage divider. A rheostat is
easily formed by floating an end terminal or connecting it to
the wiper.

BRIEF DESCRIPTION
1 1 PU The PU is a falling-edge triggered input with internal pull-up. Toggling PU will move the wiper close to RH
terminal.
2 2 PD The PD is a falling-edge triggered input with internal pull-up. Toggling PD will move the wiper close to RL
terminal.
3 3 RH The RH and RL pins of the ISL22512 are equivalent to the fixed terminals of a mechanical potentiometer. The
minimum voltage is VSS and the maximum is VCC. The terminology of RH and RL references the relative
position of the terminal in relation to wiper movement direction selected by the PU/PD input.
4 4 VSS Ground
5 6 RW The RW pin is the wiper terminal of the potentiometer which is equivalent to the movable terminal of a
mechanical potentiometer.
6 7 RL The RH and RL pins of the ISL22512 are equivalent to the fixed terminals of a mechanical potentiometer. The
minimum voltage is VSS and the maximum is VCC. The terminology of RH and RL references the relative
position of the terminal in relation to wiper movement direction selected by the PU/PD input.
