Impedance matched, voltage-mode H-bridge write drivers

A write driver for an inductive load comprising:

• first and second load terminals for connection to an inductive load;
• a driver connected to the first and second load terminals and responsive to a first control signal to supply a drive current through the load from the first load terminal to the second load terminal and responsive to a second control signal to supply the drive current through the load from the second load terminal to the first load terminal;
• a voltage-mode H-bridge connected to the first and second load terminals, the voltage-mode H-bridge being responsive to the first control signal to supply a first voltage to the first load terminal and a second voltage to the second load terminal and responsive to the second control signal to supply the first voltage to the second load terminal and the second voltage to the first load terminal;
• and
• program means responsive to the first and second control signals and configured to operate the voltage-mode H-bridge to cease supply of the first and second voltages to the respective first and second load terminals upon expiration of a predetermined time period following an initiation of the respective first and second control signal.
