ABSTRACT:
The present invention describes a voltage-mode boosting write driver circuit (160), comprising a plurality of inputs (WDP, WDN), a plurality of outputs (HWX, HWY), a transducer (L2), a flex interconnection (T1) coupled to the outputs (HWX, HWY) and to the transducer (L2), a first resistor (R15) and a second resistor (R43) coupled to the outputs (HWX, HWY) and to the transducer (L2), an H-switch (Q15, Q60, Q11, Q22) coupled to the resistors (R15, R43), and a plurality of top boosting circuits (Q42, Q47, R36, and Q43, Q48, R37) coupled to the outputs (HWX, HWY).
