Supporting Information
Overview
The BV1LExxxEFJ-C and BM2LExxxFJ-C series are the industry’s first to combine heat suppression with low ON resistance (difficult to achieve in a compact size), by optimally controlling the number of current-carrying channels using proprietary TDACC™ circuit and device technology. TDACC™ offers increased integration capability, allowing ROHM to report the industry’s first 2 channel 40mΩ (ON resistance) product in the compact SOP-J8 package.
A wide range of ON-resistance values (40/80/160/250mΩ) in both 1 channel and 2 channel configurations are offered to meet diverse customer needs. Furthermore, the contact discharge tolerance of all the products in the family is higher than that of other standard products. This adds to a safer operation inside various electronic equipment types.
Application Examples
◇ BCMs (Body Control Modules), interior/exterior lamps, engine, transmission, and other automotive electrical systems
◇ Industrial equipment such as PLCs (Programmable Logic Controllers)
Suitable for a wide range of applications in addition to the automotive and industrial systems.
