Order this document by MCCF33095/D Advance Information Integral Alternator Regulator 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 ponents 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 Variable Duty Cycle Operation MCCF33095 MC33095 INTEGRAL ALTERNATOR REGULATOR SEMICONDUCTOR TECHNICAL DATA 1 10 9 - - - - - - - Adjusts System Charging to pensate 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 FLIP- CHIP CONFIGURATION (Backside View) Back marking is oriented as shown 14 1 Simplified Block Diagram VCC 1 (12) 4 (8) Ignition Series Regulator Load Dump Detection and Protection D SUFFIX PLASTIC PACKAGE CASE 751A (SO- 14) + Bump + 9 (1) Darlington Drive 1 2 3 4 5 6 7 8 9 10 Function VCC Sense Stator Ignition Lamp Oscillator Roll- Off Ground Darlington Drive Short Circuit SO- 14 (Note 1) (12) (11) (10) (8) (5) (4) (3)(Note 2) (2) (1) (14) 6 (4) Oscillator Oscillator S Q R VReg S Q Timer R Thermal Protection 2 (11)...
