The present invention provides an apparatus for managing power within a voltage regulating circuit of a battery-powered hearing aid device includes an input terminal of a voltage regulator that receives an input voltage supplied by a battery. An output terminal of the voltage regulator provides an output voltage to a hearing aid terminal that is electrically connected to one or more electrical components of the hearing aid device. A sensing terminal of the voltage regulator senses an electrical connection between the charging device is and charging contacts of the voltage regulating circuit. The voltage regulator is configured to reduce a magnitude of the input voltage when the magnitude of the input voltage exceeds an input voltage threshold to generate the output voltage having a magnitude that is less than a maximum output voltage.

Voltage regulator and control circuit for silver-zinc batteries in hearing instruments

A hearing aid device (-) comprises a shell portion () and a battery door module (-) attached to the shell portion. The battery door module comprises a battery casing (-) and an electronics casing (-). The battery casing receives a battery () defining a battery axis (L) that extends substantially perpendicular to a longitudinal axis (L) of the battery door module. The electronics casing encloses a voltage regulator (), a printed circuit board assembly (), and at least a portion of one or more charging elements (). The battery door module also comprises at least one attachment member (-) that allows the battery door module to attach to a shell portion of the hearing aid device. The battery door module is movable relative to the shell portion between an open position and a closed position.
