DESCRIPTION
The SP4490 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. The SP4490 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 SP4490 can be easily implemented in applications driving multi-color or multi-segment
EL lamps. The SP4490
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
