TDA7073A

INTEGRATED CIRCUITS DATA SHEET TDA7073A; TDA7073AT Dual BTL power driver Product specification Supersedes data of 1994 July File under Integrated Circuits, IC01 1999 Aug 30 Philips Semiconductors Product specification Dual BTL power driver 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. TDA7073A; TDA7073AT 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).
