Product Summary

The UAA180 is a LED driver for light band displays. Corresponding to the input voltage, LEDs forming a light band are controlled similar to a thermometer scale. By using an appropriate circuitry the brightness of the LEDs can be varied and the light passage between two adjacent LEDs can be set between smooth and abrupt.

Parametrics

UAA180 absolute maximum ratings: (1)supply voltage: 18V; (2)input voltage: 6V; (3)storage temperature range: -40 to 125℃; (4)junction temperature: 150℃; (5)thermal resistance: 78K/W.

Features

UAA180 features: (1)current consumption: 8.2mA; (2)input current: 1μA; (3)voltage difference for smooth light transition: 1V; (4)voltage difference for abrupt light transition.
