O
PG2#
The PG2# output is an open-drain, active low signal
with no internal pull-up resistor. This pin can be used
to switch a load or enable a DC/DC converter. PG1#
is enabled immediately after VGATE reaches V

and the DRAIN SENSE voltage is less than 2.5V.
Each successive PGn# output (PG2#

after its predecessor, provided
that the ENPGx inputs are high. The voltage on this
pin cannot exceed 12V relative to V

. ENPGx refers
to the ENPGA, ENPGB, and ENPGC inputs.

VDD
This is the positive supply input. An internal shunt
regulator limits the voltage on this pin to approximately
12V with respect to V
SS
. A resistor must be placed in
series with the V
DD
pin to limit the regulator current
(R
