SP4501 Overview
Key Specifications
Mount Type: Chassis Mount, Panel
Pins: 17
Height: 41 mm
Length: 218 mm
Description
The SP4501 provides designers with both an electroluminescent lamp driver for backlighting and a piezotransducer driver to generate audio alert tones. The integration of an EL lamp driver and a piezotransducer driver in a single cost-effective IC reduces system cost, board space requirements and component count.
Key Features
- a low power standby mode which draws less than 1µA (typical)
- The frequency of the internal oscillator is set with a single external resistor
- The piezotranducer driver can be driven with the internally generated clock signal or an external clock signal provided by the designer
- A single inductor is required to generate the high voltage AC used to drive the EL lamp and the piezotransducer
- All input pins are ESD protected with diodes to VDD and VSS
