Hall Effect-based Linear Current Sensor ACS758xCB Substitute

Hall Effect-based linear current sensor SCT Series

Descriptions:

The SCT Current sensor ICs family provides economical andprecise solutions for ACor DCcurrent sensing.Typical applications include motor control, load detection andmanagement, power supply and DC-to-DC converter control,inverter control, and overcurrent fault detection.

The device consists of a precision，low-offset linear Hal1circuit with a copper conduction path located near the die.Applied current flowing through this copper conduction pathgenerates a magnetic field which the Hal1l IC converts into aproportional voltage.Device accuracy is optimized through theclose proximity of the magnetic signal to the Hall transducer.A precise，proportional output voltage is provided by thelow-offset,chopper-stabilized BiCMOS Hal1 IC，which isprogrammed for accuracy at the factory.

High level immunity to current conductor dV/dt and strayelectric fields, offered by Allegro proprietary integrated shieldtechnology, guarantees low output voltageripple and low offsetdrift in high-side, high voltage applications.

Features and Benefits:

• Open loop hall effect-based current sensor
