Functional Description

2.1

General

Precise magnetic switching thresholds and high temperature stability are achieved by active compensation circuits

and chopper techniques on chip. Offset voltages generated by temperature-induced stress or overmolding are

canceled so that high accuracy is achieved. The IC has an open collector output stage with 20 mA current sink

capability. A wide operating voltage range from 2.7 V to 18 V with reverse polarity protection down to -18 V makes

the TLV4946K and TLV4946-2K suitable for a wide range of applications. A magnetic south pole with a field

strength above Bop turns the output on. A magnetic north pole exceeding Brp turns it off.
