Nano Series Power Solutions

ROHM Semiconductor Nano Series Power Solutions consist of power-supply ICs designed to convert ultra-high-speed and ultra-low current technology. Nano Pulse Control™ applications convert high voltages to low voltages using a single integrated circuit to achieve simpler, more compact systems. Applications include Power over Ethernet (PoE) devices such as IP phones and wireless access points in addition to industrial equipment such as high-torque 48V motor systems. Nano Pulse Control ultra-high-speed technology enables a simplified power supply configuration in automotive lithium ion 48V batteries, leading to a high step-down ratio (24:1) from a maximum voltage of 60V to 2.5V. This results in an ON time of 9ns, well below the 120ns of conventional products.

Voltage Detectors (Reset ICs)

ROHM Semiconductor Voltage Detectors (Reset ICs) feature a highly accurate detection voltage of ±1% with low current consumption. The detectors are housed in small thin packages and offered in a wide range of detection voltages. They can be used for every kind of application equipped with controllers like micro controllers, CPU or DSP. In the ROHM voltage detector IC series CMOS and open drain output are available. Output of reset signal can be selected for connected power supply. Default SSOP packages are pin-compatible and function-compatible, so they can be used as replacements for existing ICs. All lineups are Pb-free, and meet RoHS.

Automotive Power Solutions

ROHM Semiconductor Automotive Power Solutions offer a broad portfolio of products and solutions for automotive systems, from the infotainment center and instrument cluster to powertrain and body ECUs. Also, as the demand for next-generation vehicles that embody these principles increases and automatic driving and smart cities will soon be realized, high-performance ICs and high power devices are becoming indispensable. ROHM contributes to the evolution and advancement of the automotive sector and next-generation cars by taking a quality-first approach to product manufacturing while ensuring long-term, stable supply.
