ACS70312 Linear Hall-Effect Sensor ICs

Allegro MicroSystems  ACS70312 Linear Hall-Effect Sensor ICs feature reverse battery protection and high-bandwidth analogue output for core-based current sensing. These ICs incorporate a Hall element with BiCMOS integrated circuitry, for a fully monolithic linear current sensor IC. The ACS70312 ICs are sensitive to magnetic flux density orthogonal to the IC package surface, and the output is an analogue voltage proportional to the applied flux density. These ICs are used with a ferromagnetic core to provide highly accurate current sensing. The ACS70312 ICs feature factory-programmed gain and offset drift over temperature and deliver a solution with ±1% sensitivity error and ±5mV offset error. These ICs have a high operating bandwidth ranging from DC to 240kHz and a fast 2µs response time. The ACS70312 linear Hall-effect sensor ICs operate within the −40°C to 150°C temperature range.
