Document Type and Number:
WIPO Patent Application WO/2019/140113
Kind Code:
A1
Abstract:
A load switch circuit (100) includes a driver (112) to control a gate (114) of a transistor. The gate (114) enables the transistor to deliver power to a load from a power supply (130) when the gate (114) is activated. A gate slope control (116) controls a rate of change over time of a voltage associated with the gate (114) to activate the gate (114) and to disable the driver (112) when the gate (114) is activated.
