Product Summary
The TFA9810T is a two-channel power comparator for high-efficiency class D audio amplifier systems. The TFA9810T contains two full-bridge Bridge-Tied Load (BTL) power stages, drive logic, protection control logic and full differential input comparators. By using this power comparator a compact closed-loop self-oscillating digital amplifier system or open-loop system can be built. The TFA9810T does not require a heat sink and operates using an asymmetrical supply voltage. Applications are (1)Self-oscillating or open-loop class D audio amplifier applications; (2)Flat-panel televisiosets; (3)Flat-panel monitors; (4)Multimedia systems; (5)Wireless speakers; (6)High-end CRT televisiosets.
Parametrics
TFA9810T absolute maximum ratings: (1)Voltage on pin x DIAG: VSS - 0.3 to +12 V; (2)Voltage on pin x IN1P - IN1N: -12 to +12 V; (3)Voltage on pin x IN2P - IN2N: -12 to +12 V; (4)Voltage on pin x all other pins: VSS - 0.3 to VDD + 0.3 V; (5)Electrostatic discharge voltage VINX with: -1500 to +1500 V:; (6)Electrostatic discharge voltage respect to other pins all other pins: -2000 to +2000 V.
Features
TFA9810T features: (1)Stereo full-bridge power comparator for class D audio amplifier applications; (2)No external heat sink required; (3)Operating voltage range: asymmetrical from 8 V to 20 V; (4)Thermally protected; (5)Zero dead-time switching; (6)Current-limiting (no audible interruptions).
