ML9477
1/3 or 1/4 Duty, 32-Output LCD Driver
1/20
GENERAL DESCRIPTION
The ML9477 is an LCD driver for dynamic display. It has a function to switch between 1/3 and 1/4 duty. When
1/4 duty is selected, an LCD of up to 128 segments can be driven directly; when 1/3 duty is selected, an LCD of
up to 96 segments can be driven directly.
FEATURES
Logic power supply voltage
: 2.7 to 3.6 V, 4.5 to 5.5 V
Driver power supply voltage
: 3.5 to 5.5 V
Operating temperature
:
40 to +105°C
32 segment outputs
1/4 duty
