ACS37100 datasheet (2MB pdf)
Note: This version of the datasheet incorrectly states that the fault output is open drain when the IC really has an integrated 10 kΩ pull-up on that pin, and the voltages listed in the VOC table on page 14 are half of what they should be (e.g. 100% is 1.322V, not 0.661V).
