SM8145A

Dual EL Driver

OVERVIEW

The SM8145A is an Electro Luminescent (EL) driver IC that can drive two EL displays simultaneously.

Each EL display mode ON/OFF function can be separately controlled using two enable (ENA) pins.

The luminance in each display mode can be adjusted, enabling the luminance and consumption current to be

optimized to match the application. The device is supplied in ultra-small leadless QFN-20 packages, making

driver circuit miniaturization possible.

FEATURES

I 2 separate EL display drivers
