Our radiation-hardened power management IC (PMIC) product line covers core components including operational amplifiers, low-dropout regulators (LDOs), and GaN drive circuits, which are deeply optimized for extreme environments such as high radiation, high temperature, and vibration. All products in this family are designed with radiation hardening, featuring a total ionizing dose (TID) tolerance of ≥ 1 Mrad(Si), single-event upset (SEU) immunity ≥ 37 MeV·cm²/mg, and single-event latchup (SEL) immunity ≥ 75 MeV·cm²/mg. These ICs can work in concert with ISP chips to form a complete "power supply - imaging - processing" solution, significantly shortening the development cycle of satellite payloads.
