Texas Instruments TSD5402-Q1 Class-D Sensor Driving Amplifier

Texas Instruments TSD5402-Q1 Class-D Sensor Driving Amplifier is ideal for automotive and industrial applications. These applications include, but are not limited to, resolver-based motor control, braking systems, electric power steering, servos, and flight control surfaces. The Texas Instruments TSD5402-Q1 has a wide operating voltage range and excellent efficiency, making it ideal for applications that require design flexibility. The integrated load-dump protection reduces external voltage clamp cost and size, and the onboard load diagnostics report the load status through I2C. The integrated shorted load and open load diagnostics allow systems to avoid external implementations.
