FEATURES
Supports Multiple Battery Types: Can charge and manage the power of multiple battery chemistries, including rechargeable Li−ion and AgZn batteries. Ni−MH batteries and disposable Zn−Air batteries can be detected as well. An automatic chemistry detection system recognizes the battery type. Flexibility to Support Multiple Battery Sizes: The charging parameters should be updated depending on the battery size. Parameters corresponding to one battery size can be stored in an One−Time Programmable (OTP) memory at customer site. Power Supply: Provides a clean supply to the hearing aid DSP. When a Li−ion battery is used, a step−down capacitive divider or Charge Pump is used, providing a voltage between ~1.4 V and ~0.95 V. When a AgZn battery is used, a linear regulator can be used, providing a 1.5 V max. HPM10 can also directly provide the battery voltage to the hearing aid DSP. Eg., when a Zn−Air battery is used or if the DSP can handle the voltage of a AgZn battery. Charger Communic...
