11 / 13 page 11 FN6678.1 July 16, 2009 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. 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. RL RW RH FIGURE 13.
