data sheet ADP199 rev. 0 | page 11 of 16 theory of operation the ADP199 is a high-side nmos load switch controlled by an internal charge pump. the ADP199 is designed to operate with power supply voltages between 0.9 v and 3.6 v. an internal charge pump biases the nmos switch to achieve a relatively constant, ultralow on resistance of 40 m across the entire input voltage range. the use of the internal charge pump also allows for controlled turn-on times. the switch is controlled on/off by the enable (en) input and is capable of interfacing directly with 1.2 v logic signals. the ADP199 is capable of 500 ma of continuous load current as long as t j is less than 85 c. esd protection structures are shown in the block diagram (see figure 29 ) as zener diodes. the ADP199 is a low quiescent current device with a nominal 4 m pull-down resistor on its enable pin (en). the package is a space-saving 0.8 mm 0.8 mm, 4-ball wlcsp. gnd en vin vout ADP199 charge pump and slew rate control 09672-029 4 ? figure 29. functional block diagram www.datasheet.co.kr datasheet pdf - http://www..net/
