2 / 10 page July 1994 2 Philips Semiconductors Objective specification Single BTL power driver TDA7072A/AT FEATURES • No external components • Very high slew rate • Single power supply • Short-circuit proof • High output current (0.6 A) • Wide supply voltage range • Low output offset voltage • Suited for handling PWM signals up to 176 kHz • ESD protected on all pins GENERAL DESCRIPTION The TDA7072A/AT are single 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). QUICK REFERENCE DATA ORDERING INFORMATION Notes 1. SOT97-1; 1996 September 10. 2. SOT96-1; 1996 September 10.
