TO-92 PACKAGE OPERATION

When packaged in a 3-pin TO-92, the DS2890 takes on a configuration as shown in Figure 9. As shown,

the RL and Wiper terminals and are connected to GND and the resistance between the RH terminal and

GND is varied. Note that the DS2890 charge pump must be turned off (default state) for this

configuration. (This is a power consumption issue as described in the section “POTENTIOMETER

WIPER RESISTANCE AND CHARGE PUMP CONSIDERATIONS”.)
