DIGITAL CONTROL SIGNALS
The voltage at OUT is controlled by two digital logic input signals, EN and HV_EN. HV_EN controls the state of
the VHV switch and EN controls the state of V3P3 switch. Table 1 lists the possible output states given the
conditions of the digital logic signals. State PD indicates a pulldown resistance of R
OUTDIS
to GND.
