LED Display Driver
General Description
The MM5486 is a monolithic MOS integrated circuit utilizing
N-channel metal-gate low-threshold, enhancement mode
and ion-implanted depletion mode devices. It is available in
a 40-pin molded dual-in-line package. The MM5486 is de-
signed to drive common anode-separate cathode LED dis-
plays. A single pin controls the LED display brightness by
setting a reference current through a variable resistor con-
nected to VDD.
