Description

The Allegro® ACS758 family of current sensor ICs provides economical and precise solutions for AC or DC current sensing. Typical applications include motor control, load detection and management, power supply and DC-to-DC converter control, inverter control, and overcurrent fault detection.

Features and Benefits

▪ Industry-leading noise performance through proprietary amplifier and filter design techniques

▪ Integrated shield greatly reduces capacitive coupling from current conductor to die due to high dV/dt signals, and prevents offset drift in high-side, high voltage applications

▪ Total output error improvement through gain and offset trim over temperature

▪ Small package size, with easy mounting capability

▪ Monolithic Hall IC for high reliability

▪ Ultra-low power loss: 100 μΩ internal conductor resistance

▪ Galvanic isolation allows use in economical, high-side current sensing in high voltage systems

▪ 3.0 to 5.5 V, single supply operation
