1.5 Electroluminscent Backlight Driver

The isolation feature of the HT0440 driver outputs make them ideal for driving Totem Pole N-channel MOSFETS between both positive and negative voltage rails. The low input logic current of the HT0440, together with the fact that it need not be driven from a power supply, conserves power from batteries in portable systems. The low-profile height and package size of the surface mounted HT0440 make it ideal for use in backlight systems in a portable application.
