HPM10
Features
Supports Multiple Battery Types: Can charge and manage the power of multiple battery chemistries, including rechargeable Li- ion and Ag Zn 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 Ag Zn 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 Ag Zn battery.
