DESCRIPTION
The voice coil driver L6246 is a linear power amplifier designed to drive single phase bipolar DC motors for hard disk drive applications. The device contains a selectable transconductanceloop, which allows high precision for head positioning. The power stage is composed of 2 power amplifiers, in AB class, with 4 DMOSs, with Rdson of 0.5? (Sink+Source) maximum, in a H-bridge configuration. Drive voltage for the upper DMOS FETs is provided by a charge pump circuit to ensure low Rdson.
