HV832

Preliminary

Dual High Voltage, Low Noise EL Lamp Driver

Ordering Information

General Description

Package Options

The Supertex HV832 is a high voltage driver designed for driving

two EL lamps with a combined area of 3.5 square inches. The

input supply voltage range is from 2.0V to 3.6V. The device is

designed to reduce the amount of audible noise emitted by the

lamp. The device uses a single inductor and a minimum number

of passive components. The nominal regulated output voltage

that is applied to the EL lamp is 80V.

* Product supplied on 2500 piece carrier tape reels.

Features

The HV832 has an internal oscillator, a switching MOSFET, and

two high voltage EL lamp drivers. The frequency for the switch-

ing MOSFET is set at 51KHz nominal. The EL lamp driver

frequency is set by dividing the MOSFET switching frequency by

128. An external inductor is connected between the L_Xand V_DD

pins. A 0.001 to 0.01µF, 100V capacitor is connected between

C_Sand Ground. The EL lamps are connected between EL₁to

Com and EL₂to Com.

Output voltage regulation

Enable/disable function

An input control pin is available to select various modes of the

device. Each logic pulse applied to the control pin will cause the

device to change to the next mode. The sequence for the modes

is: (1) EL₁on only, (2) EL₂on only, (3) both EL₁and EL₂on, and

(4) device shuts down. During power up of the device, the mode

will default to shut down.

Applications

❏

Mobile cellular phones

Pagers

Portable instrumentation

Portable transceivers

The switching MOSFET charges the external inductor and

discharges it into the capacitor at Cs. The voltage at C_Swill start

to increase. Once the voltage at Cs reaches a nominal value of

80V, the switching MOSFET is turned off to conserve power. The

outputs EL₁to Com and EL₂to Com are configured as H bridges

and are switching in opposite states to achieve 160V across the

EL lamp.
