Overview
INTEGRATED CIRCUITS DATA SHEET TDA7072A/AT Single BTL power driver Objective specification File under Integrated circuits, IC01 July 1994 Philips Semiconductors Objective specification Single 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 Missing Current Limiter (MCL) GENERAL DESCRIPTION TDA7072A/AT 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.
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).
