➀ Mazda and Rohm have signed a deal to develop GaN-based automotive power electronics.
➁ GaN can reduce power conversion losses and contribute to the miniaturisation of components through high-frequency operation.
➂ The collaboration aims to unveil a demonstration model within FY2025 and practical implementation for FY2027.
➀ ROHM has introduced the KA2008-B07N70A thermal printhead, designed for 2-cell Li-ion battery operation at 7.2V, suitable for A4-sized printers with a width of 210mm.
➁ Key features include optimized heating elements, reduced energy consumption by ~66% compared to 12V drive, and support for print speeds up to 100 mm/s.
➂ The thermal printhead addresses challenges in A4-sized mobile printers such as larger battery capacity needs and variations in heat distribution, ensuring high-quality prints and flexible integration options for manufacturers.
➀ ROHM推出了一款新的通用芯片电阻系列，以实现更小尺寸和更高的性能。
➁ 这个新系列包括高功率MCRS系列和低阻值、高功率MCRL系列，适用于汽车、工业和通信应用。
➂ 系列产品通过优化内部结构和新材料，提高了额定功率和温度系数，并支持小型化趋势。
➀ Rohm has expanded its general purpose chip resistors with the MCRx family;
➁ The MCRS series improves rated power and TCR characteristics;
➂ The series is available in various sizes and is compliant with the AEC-Q200 automotive reliability standard.
➀ Rohm推出了适用于GaN晶体管的8引脚隔离器，并发布了相应的半桥驱动应用电路；
➁ GaN HEMT的高侧驱动需要考虑反向电压降，以及半桥输出波形充电的过程；
➂ 通过Zener二极管和设计平衡，可以避免过充或欠充自举电容的风险。
➀ ROHM introduces a 32-bit D/A converter IC (BD34302EKV) for high-resolution audio applications, enhancing flagship audio systems with improved spatial reverberation, quietness, and dynamic range.
➁ The BD34302EKV features a new Data Weighted Averaging (DWA) algorithm, achieving a THD+N characteristic of -117dB and a signal-to-noise ratio (SNR) of 130dB.
➂ It supports sampling frequencies up to 1,536kHz and includes digital FIR filters, DSD support, and selectable device addresses.
