Power Management IC (PMIC) for Hearing Aids
Key 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.
