GENERAL DESCRIPTION
The TZA1048 is a four-channel BTL driver IC for driving motors and actuators in CD and DVD players. Two reference voltage outputs are also available for peripheral ICs such as servo and pick-up head drivers. The spindle motor control inputs to the IC can be either differential or single-ended.

FEATURES
• Two Bridge-Tied Load (BTL) driver channels for sled and spindle motors and actuators
• Pulse Width Modulation (PWM) input
• Integral thermal shut-down circuit
• Integral mute control
• Two regulated reference voltage outputs for other chips in system; 3.3 V and 1.8 V respectively
• HSOP28 package.

APPLICATIONS
• BTL driver for CD and DVD players.
