ACS70310 & ACS70311 Linear Hall-Effect Sensor ICs

Allegro MicroSystems ACS70310 and ACS70311 Linear Hall-Effect Sensor ICs incorporate a Hall element with BiCMOS integrated circuitry, providing a fully monolithic linear current sensor IC. These ICs are designed to be used in conjunction with a ferromagnetic core, providing highly accurate current sensing. ACS70310 and ACS70311 ICs have a high operating bandwidth ranging from DC to 240kHz, a fast 2µs response time, and are ideal for use in high-frequency automotive inverters and DC-DC converters where fast switching is required. The ACS70311 includes all the features of the ACS70310 with the addition of undervoltage protection (UVD) and low-voltage programming that eliminates the need for voltages greater than V_CC during user programming. The ACS70311 is backward-compatible to the ACS70310, making it a drop-in replacement. Allegro MicroSystems ACS70310 and ACS70311 Linear Hall-Effect Sensor ICs are available in an extremely thin case of 1mm thick and operate in the -40°C to +150°C temperature range.
