2 General Description
The Melexis US2884 is a bipolar Hall-effect switch
designed in mixed signal CMOS technology.
The device integrates a voltage regulator, Hall
sensor with dynamic offset cancellation system,
Schmitt trigger and an open-drain output driver, all
in a single package.
Due to its wide operating voltage range and
temperature range it is particularly suitable for use
in automotive and BLDC motor applications.
The device is delivered in a Thin Small Outline
Transistor (TSOT) RoHS compliant 3-lead
package.
