Allegro MicroSystems has extended its ACS772/3 family of high-current, integrated current sensors in through-hole and surface-mount “CB” package options with enhanced working isolation voltages. The new surface-mount, lead-form option for the CB package provides a solution for space-constrained applications.
The automotive-grade, high-voltage-isolation current sensors provide precise solutions for both AC and DC current sensing up to 400 A. Applications range from industrial robotics to electric vehicles.
Enhanced features include:
- Small footprint
- Very fast 2.5 µS response time that enables over-current fault detection, making it suited for safety-critical applications
- Enhanced working isolation voltages up to 1,300 kV+ for basic DC voltage, and 650 V+ for reinforced isolation DC voltage (Eliminates need for opto-isolators or other isolation techniques.)
- High accuracy of +/-2.1% over the lifetime of the IC
Datasheets are available for the ACS772 and ACS773.
