Abstract
A fully integrated circuit configuration that can be used to control the slew rate of a PMOS load switch is described. The circuit also integrates a multichannel temperature sensing system which can be coupled to an external set of temperature sensors, preferably non-linear PTC (positive temperature coefficient) sensors to provide both current inrush control as well as thermal overload protection. A communications data bus, such as an I2C bus, is employed to provide temperature feedback for the system controller so that the system can better control the temperature of its own environment.
