Latest Patents
One of his latest patents is a soft-start switch with voltage regulation and current limiting. This invention utilizes a combination of a MOSFET, an op-amp, a comparator circuit, and voltage dividers with capacitors. The design effectively creates a soft-start switch that incorporates current limiting features. The transconductance of the MOSFET is employed to eliminate the need for a sense resistor. The configuration of the MOSFET and op-amp as a closed-loop feedback circuit allows for precise control. The output of the op-amp is coupled to the gate of the MOSFET, while the inverting input is connected to the output of the soft-start switch through a voltage divider. A first RC circuit provides a voltage to the non-inverting input of the op-amp, which can gradually rise from a near-zero value to a reference voltage, enabling a soft-start for the load. Current limiting is achieved through a comparator circuit and voltage dividers with capacitors, ensuring that the MOSFET turns off when necessary, thus protecting the circuit.
