Power Up/Down Sequence
The device can be damaged due to improper power up / down
sequence. To prevent damage, please follow the acceptable
power up /down sequences and add two external diodes as
shown in the diagram below. The first diode is a high voltage
diode across V
PP
and V
DD
where the anode of the diode is
connected to V
DD
and the cathode of the diode is connected to
Vpp. Any low current high voltage diode such as a 1N4004 will
be adequate. The second diode is a schottky diode across V
NN
and DGnd where the anode of the schottky diode is connected
to V
NN
and the cathode is connected to DGnd. Any low current
schottky diode such as a 1N5817 will be adequate.
