Power Management ICs for Industrial

Power Management ICs for Industrial

For Long Hour Operations or Wide Temperature Environments

Ricoh offers high-reliability semiconductor devices for industrial applications that have passed both the screening at high temperature and the reliability test with extended hours. Ricoh’s industrial power management ICs are characterized to −50°C, operate in an extended temperature range of −50°C to 105°C or 125°C. Ricoh serves various customer needs including harsh environment applications where the ICs are exposed to direct sunlight, extremely cold weather conditions or long-time operations in factories. Ricoh’s industrial line of products can support applications in heat-generating motors and simple medical equipment such as AEDs.
