Publication number: 20240128851Abstract: A driver includes a low-resistance charging path between a supply voltage rail and a first output node, a high-resistance charging path between the supply voltage rail and the first output node, an inverter coupled to the first output node and configured to enable and disable the low-resistance charging path, and a high-resistance discharging path between the first output node and a second output node. The first output node is coupled to a control terminal of a pass gate transistor in some implementations. The low-resistance charging path charges a voltage on the first output node to a threshold voltage of the pass gate transistor, and the high-resistance charging path charges the voltage on the first output node greater than the threshold voltage of the pass gate transistor. The high-resistance discharging path discharges the voltage on the first output node.Type: ApplicationFiled: December 21, 2023Publication date: April 18, 2024Inventors: Bernhard Wolfgang RUCK, Ruediger KUHN, Oliver NEHRIG
