Infineon Technologies's IR4428STR establishes new standards for automotive PMIC - Gate Driver ICs with ASIL-D functional safety certification. This IC classification incorporates: 1) Redundant fault detection circuits, 2) On-chip LDO for auxiliary power, and 3) ISO 26262-compliant failure modes. Automotive applications range from 48V mild-hybrid BSG systems to steer-by-wire and brake-by-wire architectures. Benchmark tests show the IR4428STR reducing ECU wake-up time by 200ms in Volkswagen's MEB platform, while preventing latch-up during load-dump transients up to 45V. The driver also enables <1 A standby current for always-on ADAS modules.
