HV861 Overview
The HV861 is a low-noise dimmable high-voltage dual EL lamp driver designed for driving two electroluminescent (EL) lamps with a bined area of 5 in2. The input supply voltage range is from 2.5V to 4.5V. Enable input logic high can go as low as 1.5V, which allows logic interface operating from typical 1.8V supplies.
