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 resis-
tor 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.

Absolute Maximum Ratings are those values beyond which damage to the device
may occur. Functional operation under these conditions is not implied. Continuous
operation of the device at the absolute rating level may affect device reliability. All
voltages are referenced to device ground.
