ROHM released a new generation of 1 channel and 2 channel 40 V Intelligent (Smart) Low Side Switches: the BV1LExxxEFJ-C and BM2LExxxFJ-C series. The two product families are ideally designed for automotive and industrial applications. They are AEC-Q100 qualified and are suitable for systems such as car body control, engine and transmission control units, LED lighting modules or industrial PLC (programmable logic controllers).
The growing number of electronic components and digitalization of various type of equipment is driving the need to shrink the application solution size and to reduce the bill-of-materials (BOM). Besides, global issues such as CO2 emissions, or global trends such as autonomous driving, lead to stricter requirements and more complex architectures that demand an increased safety and robustness level. Conventional discrete solutions involving mechanical relays or MOSFETs can no longer meet these requirements and cannot provide protection against system failures. With greater demand for high integration, added safety features, build-in intelligence and diagnostic features, Intelligent Power Devices (IPD), also called smart switches, become an essential part for electronic systems in a continuously growing market.
ROHM addressed these market needs early on – by having developed a dedicated Smart Power process in 2014. Bringing together innovation, power efficient technology, process optimization and analog design experience, allows ROHM to offer a broad lineup of high-performance products. The integrated over-temperature, over-current and over-voltage protections, built-in diagnostic features and micro-controller feedback grant enhanced performance and reliability, superior lifetime and reliability over discrete solutions (more info).
