Note 1:
V
ENH
= 5V, V
ENL
= 0V. See V
CC
and VPP Switch Truth Tables for
programming enable inputs for desired output states.
Note 2:
Power for the V
CC
input logic and charge pump circuitry is derived
from the 5V
IN
power supply which must be continuously powered. 12V
and 3.3V power is not required to control the NMOS V
CC
switches. (See
Applications Information.)
Note 3:
The two 3V
IN
supply input pins (14 and 15) must be connected
together and the two V
CC(OUT)
output pins (1 and 16) must be connected
together. The 3V
IN
supply pins do not need to be continuously powered
and may drop to 0V when not required.
Note 4:
The V
CC
and VPP output are protected with foldback current limit
which reduces the short-circuit (0V) currents below peak permissible
current levels at higher output voltages.
Note 5:
To 90% of final value.
Note 6:
12V power is only required when VPP
OUT
is programmed to 12V.
The external 12V regulator can be shutdown at all other times. Built-in
charge pumps power the internal NMOS switches from the 5V V
DD
supply
when 12V is not present.
Note 7:
Power for the VPP input logic and charge pump circuitry is derived
from the V
DD
power supply which must be continuously powered.
Note 8:
