ISL22511_15 Datasheet, PDF (11/13 Pages) Intersil Corporation – Low Noise, Low Power, 32 Taps, Push Button Controlled Potentiometer

ISL22511
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_DB 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.
R_TOTAL with V_CC Removed
The end to end resistance of the array will fluctuate once
V_CC is removed.
