RICOH imagine.change.Global

Products for high temperature environment

Ricoh has the power management IC corresponding to the wide temperature range (-40°C to 105°C, -40°C to 125°C) in addition to a conventional operating temperature range (-40°C to 85°C).
They are suitable for the application which is used at the high temperature or self heating products such as motors, lighting tools, and so on.
Users can select products from the lineup of consumer products and another lineup categorized as "-Y" which has been conducted high temperature reliability tests.
Please refer to the classification of the products for high temperature environment for additional details.

  • *3If the SENSE pin voltage of R3117xxx1A/C and R3117Qxx2A/C make the gradual curve by rasing 0.5V/ms or less, it may cause noise when the output voltage is switched from low to high. Please use R3117xxx3A/C and R3117Qxx4A/C Series for new designs instead of these products to avoid the above problem.
  • *4R3117xxx3A/C and R3117Qxx4A/C Series may cause the malfunction (miss detection), in the case of its VDD pin voltage changes very rapidly. Please check the details in the page 11 of the datasheet.
