The Allegro ACS752CA is a robust current sensor IC that is available as a ±50 or ±100 Amp device. It operates from a 5VDC supply and has ultra-low insertion loss of only 130 µΩ (internal conductor resistance).
It is capable of sensing current in both directions (± amps). The sensed load has full AC and DC isolation due to its unique Hall effect design. This part can be used in place of the older ACS750 amp sensors.
Features:
Monolithic Hall IC for high reliability
Single +5 V supply
3 kV RMS isolation voltage
50 kHz bandwidth
Lead-free
End-of-line factory-trimmed for gain and offset
Ultra-low power loss, 130µΩ conductor resistance
Ratiometric output from supply voltage
Extremely stable output offset voltage
Small package size, with easy mounting capability
Output proportional to ac and dc currents
