TDA7073AT Datasheet | NXP Semiconductors

FEATURES - No external ponents - 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 k Hz - 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 pact 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 m A (typical 300 m A). This level of 100 m A allows for headphone applications (single-ended).
