Photocouplers for industrial automation, solar inverter applications
Semiconductor manufacturer Renesas Electronics has expanded its family of 8.2-mm creepage photocouplers with three new IGBT and intelligent power module (IPM) drivers designed for operation in harsh industrial automation equipment, solar inverter, and EV charger operating environments.

Measuring 2.5 x 2.1 mm in an LSSO5 package, the two optical isolated IGBT drivers and IPM driver reduce PCB mounting areas by up to 35% compared with other devices on the market, says the company.

"Industrial equipment and green energy system manufacturers are currently facing two core challenges: Equipment needs to get smaller, requiring downsizing for factory floor efficiency and higher functionality equipment within the same board size, while at the same time, safety standards are getting stricter," says Philip Chesley, Vice President, Industrial and Communications Business Division at Renesas. "Our expanded portfolio of small isolation devices offers customers greater layout flexibility with more options to enable longer secured creepage distance for high-voltage inverter control applications."

The RV1S9231A 2.5-A output and RV1S9207A 0.6-A output IGBT drivers and RV1S9209A active high output IPM driver come in low-profile LSSO5 packages with a 0.65-mm pin pitch, deliver 5,000 Vrms isolation voltage, and support high temperature operation up to 125°C to withstand harsh operating environments. The photocoupler trio also supports 200-V and 400-V systems with reinforced insulation to meet stringent industrial safety standards, adhering to the strict UL61800-5-1 standards for motor drive equipment.

The company says it has identified and created a system architecture for various applications where the RV1S92xxA family of products adds tangible value in the system. For instance, a new AC Drives/GP Inverters "Winning Combination" featuring the RV1S92xxA family of products enables users to downsize their industrial equipment and inverter systems that meet UL61800-5-1 standard.

The RV1S9209A, RV1S9231A, and RV1S9207A photocouplers are available now.
