Facilitates the configuration of functional safety systems required for ADAS and automated driving
Kyoto and Santa Clara, CA (GLOBE NEWSWIRE) - ROHM recently announced the availability of a power supply monitoring IC, the BD39040MUF-C, with BIST (Built-In Self Test) that supports functional safety. This IC is ideal for automotive application power supply systems requiring fail-safe measures such as electric power steering as well as sensors and cameras for autonomous driving and ADAS.
Rapid advancements in ADAS and automated driving in the automotive sector have spurred demand for functions such as collision prevention and lane assist that reduce the risk of accidents. Accordingly, product development for mounted semiconductors has to take into account how to ensure functional safety (fail-safe) in the event of failure considering self-diagnostic and other functions.
In 2017 ROHM developed an LCD chipset which supported functional safety and comprised of LCD drivers and power supply ICs ahead of the industry. In 2018 the company acquired certification of the development process under the international functional safety development standard ISO26262. At this time, when considering the safety and redundancy of systems, incorporating various self-test and monitoring functions ROHM created the industry’s first power supply monitoring IC with built-in self-diagnostic function that makes it easy to add functional safety to existing systems.
The BD39040MUF-C is a power monitoring IC that provides monitoring functions required for functional safety in the power supply systems of ADAS sensor modules. In addition to voltage monitoring functions (Power Good, reset) and a watchdog timer for monitoring the ECU essential for functional safety, ROHM’s power supply monitoring IC is the first in the industry to introduce a self-diagnostic function. By utilizing original technology, this IC makes it possible to detect potential failure of the power supply IC itself without affecting existing systems. The integration of these functions into a compact 3mm square package makes it ideal for ADAS applications demanding high miniaturization.
ROHM is committed to contributing to technological innovation in the automotive sector by developing products that achieve greater system optimization and energy savings.

The BD39040MUF-C is the first power supply monitoring IC in the industry to include a self-diagnostic function along with additional features that make it ideal for functional safety systems required for ADAS and automated driving.
Functional safety includes safety measures (concepts for ensuring safety) that minimize risk by adding functionality such as monitoring and protective equipment. In the automotive market, functional safety minimizes risk to an acceptable level in order to prevent bodily injury in the event of malfunction due to electronic system failure. There is an international standard for automotive functional safety (ISO26262). Meanwhile, protection functions frequently referred to in ICs are functions that ensure the safety of the IC itself by monitoring for internal malfunctions and destruction.
