Pin Descriptions/Functions
(Continued)
≤
0.3V, the internal NMOS FET switch turns on and the SUB
display turns off. When V
is
≥
1.4V, the internal NMOS
FET switch turns off and the SUB display turns on. The En2
pin has an internal pull down resistor, thus the internal
NMOS FET switch is normally in the on state of operation
with the SUB display turned off.
If V
and V
are
≤
0.3V and V
is
≥
1.4V, the LM3502
will enter a low I
shutdown mode of operation where all the
internal FET switches are off. If V
is not used, En2 must
be grounded or floating and use En1 along with Cntrl, to
enable the device.
Ordering Information
En1 (Bump A2):
Enable pin for the internal PMOS FET
switch (
Figure 2
: P1) during device operation. When V
is
≤
0.3V, the internal PMOS FET switch turns on and the MAIN
display is turned off. When V
is
≥
1.4V, the internal PMOS
FET switch turns off and the MAIN display is turned on. The
En1 pin has an internal pull down resistor, thus the internal
PMOS FET switch is normally in the on state of operation
with the MAIN display turned off. If V
En1
and V
En2
are
≤
0.3V
and V
Cntrl
is
≥
1.4V, the LM3502 will enter a low I
Q
shutdown
mode of operation where all the internal FET switches are
off. If V
OUT2
is not used, En2 must be grounded and use En1
a long with Cntrl, to enable the device.
