TLV4946-2L
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 TLV4946-2L 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.
