Problem
Miniaturization of wearable electronics requires efficient power and audio management solutions that minimize power consumption, solution size, and bill of materials (BOM) cost. Existing audio solutions often struggle to deliver high-quality sound and haptic feedback while maintaining long battery life and fitting into increasingly smaller form factors. Automotive and industrial battery packs need reliable battery management systems to extend battery life, improve safety, and reduce costs.
Solution
INVENTVM Semiconductor provides a range of mixed-signal ICs and DSP algorithms for power management and audio applications, focusing on efficient and innovative solutions. Their product lines, including UltraWear, PiezoDrive, UltraDAC, Type-C, and VoltaTek, address the challenges of power consumption, audio quality, and system reliability in wearables, smartphones, automotive, and industrial applications. INVENTVM's solutions include audio amplifiers for MEMS and dynamic speakers, high-fidelity DACs, Type-C charging platforms, and advanced battery management systems (BMS) for automotive and industrial battery packs. The company's turnkey IC services offer support from system specification to mass production, providing improvements and innovation to customer designs.
