Latest Patents

One of Nishimura's latest patents is titled "Setting a stable operating point and EMI control of an H-bridge output stage." This invention provides an apparatus and method for establishing a stable operating point of an H-bridge with a center shunt switch. The stable operating point allows circuits connected to the H-bridge outputs to operate under more ideal conditions, resulting in higher performance and power savings. Additionally, since common mode is a significant source of electromagnetic interference (EMI), maintaining a stable operating point in an H-bridge also helps suppress EMI.

Another notable patent is "Driver controlling slew rate and switching of a switching output stage." This invention involves drive circuits and methods that control a switching output stage. The drive circuit includes a control drive circuit connected to a control node of a low-side power transistor and a switching node of the output stage. The control drive circuit features a slew rate control circuit that adjusts the drive current on the control node of the low-side power transistor in response to the output voltage's slew rate.
