environment.

Device parameters are specified across an extended ambient

automotive temperature range: –40°C to 150°C. The ACS70310

sensor 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 leadframe plating.

• Extremely low noise and high resolution achieved via

proprietary Hall element and low-noise amplifier circuits

• Patented circuits suppress IC output spiking during fast current

step inputs

• Wide selectable sensitivity range between 0.5 and 11.5 mV/G

• User-selectable ratiometric behavior of sensitivity, quiescent

voltage, and clamps (ratiometry can be disabled), for simple

interface with application A-to-D converter (ADC)

• Precise recoverability after temperature cycling

• Open circuit detection on ground pin (broken wire)

• Customer programmable Output Voltage Clamps provide short-

circuit diagnostic capabilities

• Wide ambient temperature range: –40°C to 150°C

• Immune to mechanical stress

• Extremely thin package: 1 mm case thickness
