DESCRIPTION

· The Allegro ACS75x family offers economical and precise current sensing solutions for industrial, automotive, commercial, and communications systems.
· The device features a precision, low-offset linear Hall sensor circuit with a copper conduction path near the die.
· Current flowing through the copper path generates a magnetic field, which is sensed by the Hall IC and converted into a proportional voltage.
· The device is factory-programmed for accuracy, providing a precise, proportional voltage output.

FEATURES

· Monolithic Hall IC for high reliability.
· Operates on a single +5 V supply.
· 3 kVRMS isolation voltage between terminals 4/5 and pins 1/2/3 for up to 1 minute.
· 35 kHz bandwidth.
· Suitable for automotive temperature range.
· Factory-trimmed for gain and offset.
· Ultra-low power loss with 100 μΩ internal conductor resistance.
· Ratiometric output from supply voltage.
· Extremely stable output offset voltage.
· Compact package size with easy mounting capability.
· Output proportional to AC and DC currents.

APPLICATIONS

· Motor control.
· Load detection and management.
· Power supplies.
· Overcurrent fault protection.
· The ACS754 outputs an analog signal, VOUT, that varies linearly with the uni- or bi-directional AC or DC primary sensed current, IP, within the specified range.
· CF is recommended for noise management, with values depending on the application.
