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.

Claims (7)

1. A driver comprising:

a first buffer adapted to provide a first signal; and

a second buffer adapted to provide a second signal, wherein the first buffer and the second buffer are adapted to drive an external coil with the first signal and the second signal or drive an external first transistor with the first signal and an external second transistor with the second signal.

2. The driver of claim 1 , wherein the first transistor and the second transistor are field effect transistors.

3. The driver of claim 2 , wherein the first transistor and the second transistor are adapted to drive a coil and a capacitive load.

4. The driver of claim 1 , wherein the first signal and the second signal drive the external coil in a parallel fashion.

5. The driver of claim 3 , wherein the first signal and the second signal further drive an external capacitive load.
