Seeking  replacement for TA7279AP dual full H-bridge
Answering this question for your specific case with parts as they are now will get it closed as being too localized, so this is a more general community wiki answer.


The first thing that you need to determine is why you need the same level of integration that you currently have.  Could you get by with (2) H-bridges, or (4) half-bridges?  This will open up your options immensely.

Second, can you use discrete transistors with drivers?  For low-voltage/low-current applications this isn't really needed, but if you needed higher performance, this is crucial.

Other related drivers you could look at to replace H-bridge drivers are synchronous-drivers (often used with a half-bridge), which can be much cheaper and offer better performance, but have some limitations.

As far as manufacturers to peruse:


Linear Technology

Half/full/3-phase drivers
Good selection of some high-performance parts (low Iq, wide voltage ranges, etc)
Some parts can be pricey

Diodes Inc (Zetex)

Has a good variety of lower-power transistor packages with various combinations, e.g. Dual N, N/P, 4x N, Dual N/Dual P (H-bridge).

International Rectifier

High power transistors
High voltage bridge drivers (100-600 V)

ST Microelectronics

High power transistors
Highly integrated motor controllers with drivers and logic, however these are often very specific for door zone applications, so you might get one high-power H-bridge, two lower-power H-bridges, and some high-side drivers, and while they're pretty economical together, you're paying for it all.
