The MCCF33095 (Flip–Chip) and MC33095 (Surface Mount) are regulator control integrated circuits designed for use in automotive 12 V alternator charging systems. Few external components are required for full system implementation. These devices provide control for a broad range of 12 V alternator charging systems when used in conjunction with the appropriate Motorola Power Darlington transistor to control the field current of the specific alternator.

Both versions have internal detection and protection features to withstand 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.

• Constant Frequency with V ariable Duty Cycle Operation

• Adjusts System Charging to Compensate for Changes

in Ambient Temperature

• Slew Rate Control to Reduce EMI

• Lamp Pin to Indicate Abnormal Operating Conditions

• Shorted Field Protection

• Resumes Normal Operation Once Fault Condition Ceases

• Operation from –40°C to 170°C for Flip–Chip and –40°C to 125°C

for SO–14

• Surface Mount or Solder Bump Processed Flip–Chip Assembly Versions
