The ACS770ECB-200B-PFF-T from Allegro MicroSystems is a fully integrated Hall-effect-based linear current sensor IC providing galvanically isolated bidirectional ±200 A current measurement. The device features a 100 µOhm copper conduction path that generates a magnetic field sensed by a chopper-stabilized BiCMOS Hall IC. Proprietary digital temperature compensation greatly improves accuracy and stability over the operating temperature range without affecting the 120 kHz analog output bandwidth. The integrated shield reduces capacitive coupling from current conductor dv/dt signals, minimizing offset drift in high-voltage applications. With 4800 VRMS isolation and AEC-Q100 qualification, the device is ideal for automotive and industrial high-current sensing.

The ACS770ECB-200B-PFF-T measures current using the Hall effect. Current flowing through the internal copper conduction path (terminals 4 and 5) generates a magnetic field proportional to the current magnitude. This field is concentrated by a low-hysteresis magnetic core and detected by a Hall transducer located near the die. The Hall transducer converts the magnetic field into a voltage signal. A chopper-stabilized BiCMOS amplifier with digital temperature compensation processes this signal, providing a ratiometric analog output voltage proportional to the sensed current. For bidirectional sensing, the output sits at VCC/2 (nominally 2.5 V) at zero current and varies proportionally with current in either direction. The integrated shield between the conductor and Hall IC minimizes capacitive coupling from high dv/dt switching transients. Factory trimming ensures accuracy without external calibration.
