CAT1163WI-30-T3 Equivalent & Substitute Parts
Part Overview
The CAT1163WI-30-T3 is a supervisory circuit (PMIC) manufactured by onsemi, designed for power-on reset and simple reset functions in 8-SOIC surface mount packaging. This part monitors a single voltage channel at a 3V threshold with an active high/active low reset output configuration and a 130ms minimum reset timeout. The CAT1163WI-30-T3 is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements.
