DESCRIPTION
FEATURES
The Broadcom® ACPL-C72B, ACPL-C72A, and ACPL-C720 isolation amplifiers are designed for current sensing in electronic power converters in applications including motor drives and renewable energy systems. In a typical motor drive implementation, current flows through an external shunt resistor and the resulting analog voltage drop is sensed by the isolation amplifier. A differential output voltage that is proportional to the current is created on the other side of the optical isolation barrier. Designed to reduce power loss on the shunt resistor, the ACPL-C72x series are optimized to accept a ±50-mV input voltage range. For general applications, The high common-mode transient immunity (25 kV/μs) of the ACPL-C72x series provides the precision and stability needed to accurately monitor motor current in high-noise motor control environments, providing for smoother control (less “torque ripple”) in various types of motor control applications. Combined with superior opti...
