ACS758XCB Datasheet PDF - Allegro MicroSystems

●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 μΩinternal 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
