MM5480 LED Display Driver
General Description
The MM5480 is a monolithic MOS integrated circuit utilizing
N-channel metal gate low threshold enhancement mode
and ion-implanted depletion mode devices It utilizes the
MM5451 die packaged in a 28-pin package making it ideal
for a 3 digit display The MM5480 is designed to drive
common anode-separate cathode LED displays A single
pin controls the LED display brightness by setting a refer-
ence current through a variable resistor connected either to
VDD or to a separate supply of 11V maximum
