SGS Thomson sells the L9335 and L9336 Injector Drivers. The former is a 2.4 amp / 0.6 amp peak/hold, and the latter is a 4 amp / 1 amp peak/hold. The pinout looks the same as the Motorola MC3484S2-2 and MC3484S4-2. Cherry Semiconductor also sells the part (CS-452 and CS-453). Bryan Zublin bzublin at gi.com
