High-efficiency power management ASIC for hearing aids

The power management ASIC is developed for battery powered implanted hearing aids. The ASIC converts the power of both single or stacked ZnO2 or Li-Ion batteries to power the audio capture chain including ADC, a class D audio driver chain and the digital audio processing. It also manages the inductive communication between the hearing aid and the implant.

FEATURES

  • Versatile high-efficiency buck/boost DC-DC converter
  • Audio capture chain (amps and 12-bit ADC)
  • Audio quality class D output driver
  • Battery safety features and low leakage
  • Low power consumption
  • 0.18um CMOS technology
