HPM10 Power Management IC for Hearing Aids
●Introduction
■HPM10 is a Power Management IC (PMIC) that provides ahigh-performance solution for rechargeable batteries in hearing aids and hearing implant devices. Responsible for generating the voltage needed by the hearing aid, it manages the charging algorithms such that the battery autonomy and the number of charging cycles are optimized. The rechargeable chemistries supported include silver-zinc (AgZn), and lithium-ion (Li-Ion). HPM10 also detects zinc-air (Zn-Air) and nickel-metal hydride (Ni-MH) batteries but doesn’t charge them.
■HPM10 includes a Charger Communication Interface (CCIF) to inform the hearing aid charger about the charging progress. Other battery information such as voltage levels, current levels, temperature, and different types of battery failures can also be communicated.
■HPM10 has the flexibility that allows easy integration into various types of hearing aids. It can be used without any connection to the main hearing aid digital signal processing (DSP), and manage the switch on and off operation, as well as the battery EOL control by-itself. Closer integration and communication with the main hearing aid DSP can also be obtained.
