SM8142B EL Driver OVERVIEW The SM8142B is a transformer-less electroluminescent (EL) driver IC, capable of driving sheets up to 30cm2 in size. It employs a high-efficiency driver output circuit configuration to control power dissipation. It is available in ultra-small 8-pin SON (Small Outline Non-leaded) packages*, making possible the construction of small, thin, low-power driver units. * : SM8142BD FEATURES ▪ Dedicated EL driver ▪ Noise-less smooth drive waveform ▪ High-efficiency output circuit ▪ Stand-by function ▪ Stable temperature characteristics ▪ Ultra-small package ▪ 1.6 to 5.5V supply voltage ▪ 0.3mA typ.
