... 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. V ...

... The falling-edge triggered input with internal pull-up. Toggling PD will move the wiper close to RL terminal The RH and RL pins of the ISL22511 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum voltage and the maximum 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 ...

... RH RL The V ramp rate specification is always in effect. CC Pin Descriptions RH and RL The RH and RL pins of the ISL22511 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum voltage is V and the maximum and RL references the relative position of the terminal in relation to wiper movement direction. ...

... 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 t time window of 15ms, see “ ...
