Electrification of automobile by RICOH power management IC

Quality Rank for Automotive Applications

Quality Rank for Automotive Applications

Various equipment with varying quality requirement levels are installed in automobiles, ranging from equipment that controls running, turning, and stopping to car accessories such as audio and navigation.

Ricoh's automotive power management IC is divided into three quality ranks according to the application so that we can provide products matching the customer's requested quality. In addition, the rank 2 for general equipment is further divided into three classes according to the operating temperature range, and therefore we prepare products in total of five quality categories.
Please use the product of the quality rank and class suitable for each purpose.
