MOTOROLA MCCF79076

Order this document from Analog Marketing
The MCCF79076, in conjunction with an appropriate Motorola Power
Darlington Transistor, provides an economical solution for automotive
ignition applications. The MCCF79076 offers optimum performance by
providing closed loop operation of the Power Darlington in controlling the
ignition coil current.
The MCCF79076 incorporates Flip–Chip Technology which involves the
formation of solder bumps, rather than traditional wire bonds, to establish
mechanical and electrical contact to the semiconductor chip. This process
affords a unique device having improved reliability at elevated operating
temperatures.
