ACS758xCB
Thermally Enhanced, Fully Integrated, Hall Effect-Based
Linear Current Sensor IC with 100 μΩ Current Conductor
Features and Benefits Description
▪ Industry-leading noise performance through proprietary The Allegro® ACS758 family of current sensor ICs provides
amplifier and filter design techniques economical and precise solutions for AC or DC current sensing.
▪ Integrated shield greatly reduces capacitive coupling from Typical applications include motor control, load detection and
current conductor to die due to high dV/dt signals, and management, power supply and DC-to-DC converter control,
prevents offset drift in high-side, high voltage applications inverter control, and overcurrent fault detection.
▪ Total output error improvement through gain and offset
The device consists of a precision, low-offset linear Hall
trim over temperature
circuit with a copper conduction path located near the die.
▪ Small package size, with easy mounting capability
Applied current flowing through this copper conduction path
▪ Monolithic Hall IC for high reliability
generates a magnetic field which the Hall IC converts into a
▪ Ultra-low power loss: 100 μΩ internal conductor resistance
