DESCRIPTION
The SP4491 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 SP4491 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 SP4491 can be easily implemented in applications driving multi-color
or multi-segment EL lamps. The SP4491
operates from a +2.2V to +6.0V battery source. The
device features a low power standby mode which draws less than 1
μ
A. 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 V
DD
and V
SS.
