Family of photocouplers ideal for harsh industrial applications

26-07-2019 | Renesas | Power

Renesas Electronics has released three new 15Mbps photocouplers created to endure the harsh operating conditions of industrial and factory automation equipment. The trend toward higher voltage, compact systems is forcing stricter International safety standards and eco-friendly solutions that demand smaller ICs with lower power consumption. The RV1S9x60A family satisfies this requirement with best-in-class IFHL ratings: the RV1S9160A (SO5) operates at 2.0mA, the RV1S9060A (LSO5) at 2.2mA, and the RV1S9960A (LSDIP8) at 3.8mA.

Lower power consumption enables the photocouplers to suppress power supply heat generation meaningfully. With high-temperature operation up to 125C allows board space savings by mounting the photocoupler near the IGBT or MOSFET power device. The devices are aimed at DC to AC power inverters, AC servo motors, robotic arms, PLCs, solar and wind input power conditioners, and battery management systems for energy storage and charging.

“Our newest RV1S9x60A 15Mbps photocouplers provide the ultimate balance of low power, high speed, and high noise rejection today’s customers require,” said Philip Chesley, vice president, Industrial Analog and Power Business Division, Renesas Electronics Corporation. “The devices also comply with and surpass the stringent safety requirements of the UL61800-5-1 and UL61010-2-201 standards, giving manufacturers the best-in-class features and confidence they need to accelerate product development.”
