4. ROHM tools significantly reduce application development time

Using ROHM’s reference designs together with ROHM Solution Simulator minimizes application development manhours at each design stage (e.g., circuit/board/noise/thermal design, simulation).

Reference Designs

The available reference designs (which include the BD9P series) have undergone thermal and EMC testing, along with measurement of standard electrical characteristics, and cover power supply systems required for ADAS and infotainment functions. In addition to evaluation reports, various tools such as design data, onboard simulation models, and PCB CAD symbols are offered, facilitating evaluation when used with the REFRPT001-EVK-001 reference board.

Available Tools

• Design data (e.g., circuit schematics, BOM, PCB data)
• Simulation models (e.g., SPICE, thermal)
• PCB library (e.g., CAD tool symbols, footprints)

ROHM Solution Simulator

ROHM Solution Simulator is web simulation tool that enables complete circuit verification of power devices (power semiconductors), driver ICs, and power management ICs on the solution circuits. ROHM supports development by offering reference circuits including the new products in the form of cut-out reference designs, along with various tools.

BD9P Series Product Lineup

The BD9P series is offered in 3.3V/5.0V/variable output voltages to support a wide range of circuits.

Application Examples

• ADAS sensors, cameras, and radars
• Car infotainment, instrument clusters, BCM (Body Control Modules), etc.
• Automotive applications requiring high efficiency, superior reliability, and greater compactness

Availability: In mass production

Nano Pulse Control

Nano Pulse Control refers to ultra-fast pulse control technology achieved by combining three advanced analog technologies, circuit design, layout, and processes utilizing ROHM’s vertically integrated production system. This allows a single power supply IC to convert from a high voltage to a low value, which previously required two or more ICs, contributing to greater miniaturization and simplification in applications that drive both 12V (e.g., gas-powered vehicles, xEVs) and 48V systems (e.g., mild hybrid vehicles, industrial robots, base station sub power supplies).
