HPM10: Power Management IC (PMIC) for Hearing Aids

HPM10 is a Power Management IC (PMIC) that provides a high-performance solution for rechargeable batteries in hearing aids and cochlear implant devices. Responsible for generating the voltage needed by the hearing aid, it manages the charging algorithms so that the battery autonomy and the number of charging cycles are optimized. HPM10 supports silver-zinc (AgZn) and lithium ion (Li-ion) rechargeable chemistries. It also detects zinc-air (Zn-air) and nickel-metal hydride (Ni-Mh) disposable batteries. HPM10 is supported by a comprehensive suite of development tools, which includes hardware, software, and technical documentation.

Features
  • Battery Type Flexibility: Automatically detects and charges rechargeable batteries (incl. Silver-Zinc (AgZn) and Lithium Ion). Also detects Zinc-Air (Zn-Air) and Nickel-Metal Hydride (Ni-Mh) disposable batteries.
  • High-Efficiency Power Regulation: Optimized regulators to minimize dissipated power from the battery to the hearing aid.
  • Ultra-Low Power Consumption: Offers a Deep Sleep current consumption of 15 nA to maximize the shelf life of a sealed battery
  • Non-Volatile Memory (OTP): Stores charging parameters , trim codes, and general product-specific settings.
  • Communication Interface: Includes a Charger Communication Interface (CCIF) to provide battery information directly to the hearing aid (eg. Charging progress, voltage and current levels, temperature, and failures).
  • Design Flexibility: Available in ultra-miniature WLCSP packaging for easy integration into various types of hearing aids and cochlear implants.
Applications
  • Supports and manages rechargeable batteries in hearing aids
End Products
  • Hearing Aids
  • Cochlear Implants
