GENERAL DESCRIPTION

The TDA7073A/AT are dual power driver circuits in a BTL

configuration, intended for use as a power driver for servo

systems with a single supply. They are specially designed

for compact disc players and are capable of driving focus,

tracking, sled functions and spindle motors.

Missing Current Limiter (MCL)

A MCL protection circuit is built-in. The MCL circuit is

activated when the difference in current between the

output terminal of each amplifier exceeds 100 mA (typical

300 mA). This level of 100 mA allows for headphone

applications (single-ended).
