Abstract: An interface driver circuit includes a plurality of delay cells. Each delay cell includes a data input, a delayed data output configured to communicate with the data input of an adjacent one of the plurality of delay cells. A delay time input is configured to set a delay value between receiving data at the data input and generating the delayed data output. A plurality of predrivers is configured to receive an output enable signal. A plurality of predrivers is configured to receive a corresponding one of the plurality of delayed data outputs. A plurality of predrivers is configured to generate a predriver output signal based on the output enable signal and the corresponding one of the plurality of delayed data outputs. The output enable signal enables and disables the plurality of predrivers and is independent of data of each delayed data output.

Abstract: A circuit is adapted to activate a writer head of a data storage media drive during both the boost periods as well as the steady state periods. The current supplied to the writer head during the boost periods exceeds the steady state current and flows between positive and negative voltage supplies so as to provide the required magnetic flux change in the inductor disposed in the write head. During the steady state periods, a switch circuit is turned on to provide a second current path across the writer head. During the steady state periods, the current flows between the positive voltage supply and the ground to reduce power consumption. The switch circuit is turned off during the boost periods.

Abstract: An interface driver circuit comprises N cascaded delay cells, each including a data bit input, a delayed data bit output that communicates with the data bit input of an adjacent one of the N cascaded delay cells, and a delay time input that sets delay values between receiving data at the data bit input and generating the delayed data bit output. N predrivers receive an output enable signal that is independent of the data, receive a corresponding one of the N delayed data bit outputs and generate a predriver output signal based on the output enable signal and the corresponding one of the N delayed data bit outputs.

Abstract: A small computer system interface (SCSI) driver circuit having a programmable slew rate comprises N cascaded delay cells each including a data bit input, a delayed data bit output that communicates with the data bit input of an adjacent one of the N cascaded delay cells, and a delay time input that receives a programmable delay time value for setting a variable delay between receiving data at the data bit input and generating the delayed data bit output. N predrivers receive an output enable signal and a corresponding one of the N delayed data bit outputs and generate a predriver output signal based on the output enable and the corresponding one of the N delayed data bit outputs. N drivers have inputs that receive predriver output signals from corresponding ones of the N predrivers. An output port communicates with outputs of the N drivers.
