MODE pin = high to low (LP to HD), VO = 3.8 V

Delay time, MODE pin falling

tLP-HD is defined as the time taken for the

tLP-HD

(low-power mode to high-drive mode)

quiescent current to increase from 110% of its

170

value in LP mode to 90% of its value in HD

mode.

tHD-LP is defined as the time taken for the

Delay time, MODE pin rising

quiescent current to decrease from 90% of its

tHD-LP

300

(high-drive mode to low-power mode)

value in HD mode to 110% of its value in LP

mode.
