General Description
The Supertex HV809 is an off-line, high voltage, EL lamp
driver integrated circuit designed for driving EL lamps of
up to 350nF at 400Hz. The input supply voltage can be a
rectified nominal 120V AC source or any other DC source
up to 200V. The HV809 will supply the EL lamp with an
AC square wave with a peak-to-peak voltage of two times
the input DC voltage.
The HV809 has two internal oscillators, a low voltage output
linear regulator, and a high voltage output H-bridge. The
high voltage output H-bridge frequency is set by an external
resistor connected between the REL-Osc and GND pins.
The EL lamp is connected between pins VA and VB. For
the HV809 in the 8-pin package, an external RC network
can be connected between the oscillator’s Osc1 and Osc2
pins to pulse the EL lamp on and off.
For detailed circuit and application information please refer
to Application Note AN-H36.
