Supertex inc. HV809 Off-Line, High Voltage EL Lamp Driver Features General Description Processed with HVCMOS technology The Supertex HV809 is an off-line, high voltage, EL lamp driver integrated circuit designed for driving EL lamps of up to Input voltage up to 200V DC 350nF at 400Hz. The input supply voltage can be a rectified 400V peak-to-peak output voltage nominal 120V AC source or any other DC source up to 200V. 2 2 Output load up to 350nF (100in for 3.5nF/in lamp) The HV809 will supply the EL lamp with an AC square wave Adjustable output lamp frequency with a peak-to-peak voltage of two times the input DC voltage. Adjustable on/off pulsing frequency 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- Applications tor connected between the REL-Osc and GND pins. The EL lamp is connected between pins VA and VB. For the HV809 in Electronic organizers the 8-pin package, an external RC network can be connected Handheld portable computers between the oscillators Osc1 and Osc2 pins to pulse the EL Display signs lamp on and off. Portable instrumentation equipment For detailed circuit and application information please refer to Application Note AN-H36.
