This design features a wireless headphone with a cradle solution. It includes an ultra-low power 48MHz Arm® Cortex®-M23 MCU in conjunction with a best-in-class, high-efficiency power solution that enables extended battery life.

System Benefits:

  • Advanced security, connectivity and flexible software
  • Integrated analog front-end (AFE) enables reduction in BOM costs and PCB size by eliminating several analog components
  • Compact for space-limited applications
  • Highly efficient and low quiescent current power solution
  • The P9235A wireless power transmitter features an integrated Arm Cortex-M0 processor, which provides a high level of programmability, and empowers users to customize features, such as LED patterns, buzzers and FOD threshold settings
