Because the L293D uses bipolar transistors, it can generate significant heat, especially when running near its peak current (1.2A). For long-duration or high-load operations, this can be a problem. While it includes thermal shutdown to prevent damage, heavy use will cause the shield to get very hot and may cause intermittent operation.
