ISL9221 Datasheet | Renesas

feature in providing a limited amount of current to system architecture while protecting the system from destructively high voltage. The device contains Thermal regulation and protection to provide additional safety features of this device. When the temperature exceeds +125°C, the current will fold back to reduce and control the die temperature. Ordering Information PART NUMBER (Note) PART TEMP. MARKING RANGE (°C) PACKAGE PKG.
