Abstract
A driver including first and second buffers connected in parallel between a power source and a return path. In one configuration, the buffer outputs are commonly connected to an external coil and optionally a capacitive load. In another configuration, the buffers' outputs independently drive first and second external transistors. The external transistors are in series between a supply voltage source and its return path.
