[Allegro]

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
▪ 120 kHz typical bandwidth
▪ 3 μs output rise time in response to step input current
▪ Output voltage proportional to AC or DC currents
▪ Factory-trimmed for accuracy
▪ Extremely stable output offset voltage
▪ Nearly zero magnetic hysteresis
