Patent number: 10298211Abstract: A level shifter does not require any DC (standby) current consumption and has a fast operation with low propagation delay. The level shifting from input to output voltage ranges is performed by a pair of level shifting capacitors. The input-output power voltages domains are unrestricted and flexible. DC isolation is deployed between power domains. Symmetrical rise/fall times are without duty cycle distortion. Over voltage stress is reduced by using metal capacitors. Finally the level shifter does not use high-voltage devices for level shifting purpose. Embodiments of level shifters provide one-way level shifting and bi-directional level shifting.Type: GrantFiled: November 4, 2015Date of Patent: May 21, 2019Assignee: Dialog Semiconductor GmbHInventor: Mykhaylo Teplechuk

Patent number: 9509300Abstract: Automatic and robust anti-shoot-through glitch-free operation of half-bridge control pre-driver and power stage circuits have been achieved by using multiple feedback control signals. These feedback signals are taken both from the gates of power devices on high side and low sides and from the gates of one or more devices on both high side and low side that enable power device ON state. No duty cycle limitation is required of the input signal. The control logic uses NAND/NOR RS latches. The solution disclosed can readily be scaled to higher order of feedback loops providing even greater level of robustness.Type: GrantFiled: May 12, 2014Date of Patent: November 29, 2016Assignee: Dialog Semiconductor GmbHInventor: Mykhaylo Teplechuk
