1. Summary
LH1537
2
The-LH1537
is a 240 output
common driver
LSI suitable
for driving
dot matrix
LC panels using low voltage
segment driving
method.
With the use of SST (Super Slim TCP) technology,
it is possible
to decreace
the size of the frame section
of the LCD module.
Combined with the Segment Driver
LHlSSE(SST)
and Power Supply
IC LR3694,
it
is possible
to constitute
a low power consumption
LCD module.
2. Features
Supply voltage
for LC drive
: +20.0 to +45.0 v
: 240
Number of LC drive outputs
: 3
Output level
Correspond
to low voltage
segment driving
method
Controllable

from Controller
Low power consumption
Supply voltage
for the logic
system : +2.4 to +5.5 V
Low output
impedance
: 600 R(Typ.)
Shift
clock frequency
: 4.0 MHz(Max.)(VDD=+5
V&10 X)
: 3.0 HHz(hax.)(Voo=+2.4
to +4.5 V)
It is possible
to select
the number of LC drive outputs
(240 outputs
or 200 outputs)
