General Description

Features

EC2621 Hall-effect sensor is a temperature stable, stress-

resistant, Low Tolerance of Sensitivity micro-power switch.

Superior high-temperature performance is made possible

through a dynamic offset

cancellation

that

utilizes

chopper-stabilization. This

method

reduces

the

offset

voltage

normally

caused

by

device

over

molding,

temperature dependencies, and thermal stress.

EC2621 is special made for low operation voltage, 1.65V,

to active the chip which is includes the following on a

single

silicon

chip: voltage regulator,

Hall

voltage

generator,

small-signal amplifier,

chopper

stabilization,

Schmitt trigger, CMOS output driver. Advanced CMOS

wafer fabrication processing is used to take advantage of

low-voltage requirements, component matching, Very low

input-offset errors, and small component geometries. This

device requires the presence of omni-polar magnetic fields

for operation.

The package type is in a Halogen Free version has been

verified by third party Lab.
