Product Overview

The MAX14521EETG+ is a quad, high voltage EL lamp driver with I2C interface in 24 pin TQFN package. This quad output high voltage DC-AC converter drives four electroluminescent (EL) lamps. Input range allows device to accept a variety of voltage sources such as single-cell lithium-ion (Li+) batteries. The lamp outputs of device generates up to 300Vp-p for maximum lamp brightness. The high voltage outputs are ESD protected up to ±15KV human body model (HBM), ±6KV contact discharge and ±8KV air gap discharge as specified in IEC 61000-4-2. It uses a high voltage full bridge output stage to convert high voltage generated by boost converter to a sinusoidal output waveform and utilizes a high frequency spread spectrum oscillator to reduce amount of EMI/EFI generated by boost converter circuit. It is ideal for battery-powered devices with 100nA shutdown current. It is used in keypad backlighting, LCD backlighting, PDAs and smartphones.
  • Supply voltage range is 2.7V to 5.5V
  • Operating temperature range from -40°C to 85°C
  • Integration reduces required board space, low number of needed discrete components
  • Enhances lamp performance, 300Vp-p maximum output for highest brightness
  • ±3% EL output frequency accuracy for truest EL panel colour
  • Individually adjustable output brightness ramping rate and individual dimming control
  • Audio input for dynamic lighting effects
  • I²C interface for control of brightness, EL frequency, boost frequency and shape
  • Eases system integration, sinusoidal output for low audible noise
  • High frequency spread spectrum oscillator reduces EMI/EFI generation
