General Description
The ZSP4491 electroluminescent lamp driver provides
designers of cell phones PDA’s and other handheld,
portable electronic devices with an integrated solution for
driving two EL lamps independently or concurrently. The
ZSP4491 is designed with our proprietary high voltage
BiCMOS technology. The ZSP4491 reduces system cost,
component count and board space requirements over a
discrete 2-EL driver approach. The EL lamps operate in
opposite phase so the ZSP4491 can be easily implemented
in applications driving multi-color or multi-segment EL
lamps. The ZSP4491 operates from a +2.2V to +5.0V
battery source. The device features a low power standby
mode which draws less than 1mA. The frequency of the
internal oscillator is set using a single external resistor. A
single external inductor is required to generate the high
voltage AC outputs to drive the EL lamps. All input pins are
ESD protected with internal diodes to VDD and VSS.
