SP4491 Overview
Key Specifications
Mount Type: Chassis Mount
Max Operating Temp: 70 °C
Min Operating Temp: -55 °C
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.
Key Features
- a low power standby mode which draws less than 1µA
- 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
