The MCCF33095 (Flip–Chip) and MC33095 (Surface Mount) are regulator control integrated circuits designed for use in automotive 12 V INTEGRAL alternator charging systems. Few external components are required for full
ALTERNATOR
system implementation. These devices provide control for a broad range of 12 V alternator charging systems when used in conjunction with the REGULATOR appropriate Motorola Power Darlington transistor to control the field current of the specific alternator. SEMICONDUCTOR Both versions have internal detection and protection features to withstand TECHNICAL DATA extreme electrical variations encountered in harsh automotive environments. Flip–Chip Technology allows the MCCF33095 to operate at higher ambient temperatures than the surface mount version in addition to withstanding severe vibration and thermal shock with a high degree of reliability.
