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
