(1) 400 mA/500 mA current level can only be activated when DIR = 0, Tx-MASK = 1 and GPIO input is set high. This
operating mode only applies to TPS61050.
(2) MODE_CTRL[1:0] = 00, VOUT is one body diode below the input voltage, I
Q
= 0.3 µ A (typ).
(3) MODE_CTRL[1:0] = 00, rectifier MOSFET is turned on shorting VOUT and SW, I
Q
= 150 µ A (typ).
