Patent ID: 7940101

Claim:
An apparatus for slew rate control, the apparatus comprising: a load switch to output a load voltage to a load; and a switch controller coupled to the load switch, the switch controller to generate a switch control signal in response to an enable signal, the switch control signal to control operation of the load switch, wherein the switch controller comprises: a resistive network; and a resistive network controller coupled to the resistive network, wherein the resistive network controller is configured to independently control switches within the resistive network, wherein the resistive network controller comprises: a counter to advance a count in response to a clock signal while the enable signal is asserted; and a decoder coupled to the counter, the decoder to generate a plurality of resistive network control signals, wherein the decoder sends one of the resistive network control signals to a corresponding switch within the resistive network via a corresponding resistive network control channel coupled between the decoder and the corresponding switch; wherein the switch controller is configured to control a slew rate of the load switch according to a plurality of discrete slew rate levels.
