Allegro MicroSystems has announced its latest Hall-effect current sensor IC with highest speed and accuracy in > 400A sensing applications to date.

Ideally suited to hybrid and electric vehicle inverter applications that need high accuracy sensing to 1000A and above, the ACS70310 offers a robust solution with diagnostic functions that can help improve functional safety and reliability.

The ACS70310 linear current sensor IC achieves +/-1.2% sensitivity and +/-5mV of offset error over the automotive temperature range of -40°C to 150°C. By providing both short circuit and over-current detection, the ACS70310 delivers analogue output voltage proportional to the applied magnetic field.

Providing improved safety, the output of the ACS70310 has a response time of 2us and a typical operating bandwidth of 240kHz. The current sensor IC is also extremely robust.
