Fuel injector driver from Cherry Semiconductor

Regarding peaking and hold in general ...

The IC's that are currently available on the open market are (probably) silicon
built to a specific manufacturers (ie. Delco, Ford or Chrysler).  Ford does but
IC from both Motorola and Cherry (I don't know which from whom).  The benefits
you list were the reasons for this type of driver.

I think we (Ford) have now switched completely to "high" impedance injectors
(ie. >= 12 ohms) which only draw a nominal 1 amp and don't require the peak and
hold drivers.  Power MOSFET are only recently being used because in the past
they were too expensize.
