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 an analog 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.
This current sensor IC is also extremely robust. The
“Our current sensor ICs are leading the market in inverters in hybrid and fully electric vehicles—thanks to our focus on innovation in the industry,” explains Shaun Milano, Director of Allegro’s Current Sensor Product Line. The ACS70310 offers the
The ACS70310 is field programmable by the customer to optimize both the sensitivity and offset after assembly into the final system. Several other parameters are also programmable (see the datasheet for complete details). Customers can also order Allegro-programmed devices and conduct fast and efficient software calibration of both
The sensor IC incorporates a highly sensitive Hall element with a BiCMOS interface integrated circuit that employs a low noise, small-signal high-gain amplifier, as well as a low-impedance output stage, and a proprietary, high bandwidth dynamic offset cancellation technique.
The IC is provided in an extremely thin case (1 mm thick), 4-pin SIP (single in-line package, suffix KT) that is lead (Pb) free, with 100% matte tin lead frame plating.
