Granted I forgot the external clamp diodes, but I can't see why you think using the L293D is an advantage over the Rohm BD62x1. Here are compairsons that appear to favor the BD62x1:

Operating range: BD62x1 will run with Vss 3 to 36 v; L293D is 4.5 to 36. This is important to me since my board supply is 3.95 vdc (3 ea AA NiMH batteries);

Quantity 1 price at Mouser: BD62x1 = $1.50; L293D = $5.12....even adding the 4 ea clamp diiodes (1N4001??) BD62x1 approach is a lot cheaper;

Low Stanby current: BD62x1 has standby mode = 10 microAmps; L293D has quiescent current total (Vss + Vx) of at least 18 milliAmps dey pending on logic setting.....this is too high for battery operation.

Based on above comparison I wouldl really appreciate your opinon as to why the L293D is preferable. ???
