Abstract
Techniques for power Field Effect Transistor (power-FET) gate drivers are described herein. In an example embodiment, a USB-enabled system comprises a first and second power paths and an IC controller coupled to control the first and second power paths, where the first and second power paths are external to the IC controller and the IC controller is configured to operate both an N-channel power-FET in the first power path and a P-channel power-FET in the second power path.
Claims7
A system comprising:
- a first power path comprising an N-channel power-Field Effect Transistor (power-FET);
- a second power path comprising a P-channel power-FET;
- an integrated circuit (IC) controller coupled to control the first power path and the second power path, wherein the first power path and the second power path are external to the IC controller, and wherein the IC controller is configured at least to:
- in a first state, operate to turn and maintain ON the N-channel power-FET;
- in a second state, operate to turn OFF the N-channel power-FET and to turn and maintain ON the P-channel power-FET;
- and
- in a third state, operate to turn OFF the P-channel power-FET.
