Overview

MM5450/5451 Micrel MM5450/5451 LED Display Driver General Description The MM5450 and MM5451 LED display drivers are monolithic MOS IC’s fabricated in an N-Channel, metal-gate process.
The technology produces low-threshold, enhancement-mode, and ion-implanted depletion-mode devices.
A single pin controls the LED display brightness by setting a reference current through a variable resistor connected to the supply.
Features • • • • • • • • Continuous brightness control Serial data input No load signal requirement Enable (on MM5450) Wide power supply operation TTL compatibility 34 or 35 outputs, 15mA capability Alphanumeric capability Applications • • • • Industrial control indicator Relay ...
