For mobile label printers and payment terminals, 2-cell Li-ion battery thermal printers have become mainstream due to their printing speed and print quality.

Key Points: 
  • For mobile label printers and payment terminals, 2-cell Li-ion battery thermal printers have become mainstream due to their printing speed and print quality.
  • Single-cell Li-ion battery drive allows printers to be made smaller, lighter, and more energy efficient, but drawbacks such as slower printing speed and shorter battery life prevent widespread use.
  • In response, ROHM developed a thermal printhead that can achieve the same print output as a 2-cell drive even with a single Li-ion battery cell.
  • ROHM also succeeded in reducing the applied energy required for printing by about 30% over existing single-cell drive thermal printheads.

SBDs with a trench MOS structure provide lower VF than planar types and enable higher efficiency in rectification applications.

Key Points: 
  • SBDs with a trench MOS structure provide lower VF than planar types and enable higher efficiency in rectification applications.
  • One drawback of trench MOS structures, however, is that they typically feature worse trr than planar topologies, resulting in higher power loss when used for switching.
  • Expanding on the four existing conventional SBD lineups optimized for a variety of requirements, the YQ series is ROHM’s first to adopt a trench MOS structure.
  • The trench MOS structure is created by forming a trench using polysilicon in the epitaxial wafer layer to mitigate electric field concentration.

Santa Clara, CA and Kyoto, Japan, Feb. 07, 2024 (GLOBE NEWSWIRE) -- ROHM Semiconductor today introduced the new LMR1002F-LB zero-drift operational amplifier (op amp).

Key Points: 
  • Santa Clara, CA and Kyoto, Japan, Feb. 07, 2024 (GLOBE NEWSWIRE) -- ROHM Semiconductor today introduced the new LMR1002F-LB zero-drift operational amplifier (op amp).
  • It is designed for industrial and consumer electronics devices and minimizes both input offset voltage and input offset voltage temperature drift.
  • At the same time, the input offset voltage temperature drift, which varies according to temperature and time, is difficult to compensate for.
  • Enabling accurate amplification of measured sensor signals without being affected by environmental changes such as temperature contributes to high accuracy control of industrial equipment in factories.
