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 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 Variable 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
