MPU voltage supervisor — active, no end-of-life concern
The ICL7665AIJA: This part sits in the Power Management (PMIC / Gate Driver) category and is specified as a voltage-monitor supervisor — it watches the supply rail and asserts a reset or interrupt when the voltage drifts outside the programmed threshold.
Bulk packaging — typical for through-hole or volume orders
Shipped in Bulk, which usually means tubes or trays rather than tape-and-reel — common for through-hole packages or when ordering in larger quantities for production runs.
