Micropower CMOS Output Hall Effect Switch
EC2621
General Description
Features
EC2621 Hall-effect sensor is a temperature stable, stress- _{ CMOS Hall IC Technology}
resistant, Low Tolerance of Sensitivity micro-power switch. _{ Strong RF noise protection}
Superior high-temperature performance is made possible
through a dynamic offset cancellation that utilizes ^{ 1.65 to 3.5V for battery-powered applications}
chopper-stabilization. This method reduces the offset  Omni polar, output switches with absolute value of
voltage normally caused by device over molding, _{North or South pole from magnet}
temperature dependencies, and thermal stress.
 Operation down to 1.65V, Micro power consumption
 High Sensitivity for reed switch replacement
EC2621 is special made for low operation voltage, 1.65V, _applications
to active the chip which is includes the following on a
single silicon chip: voltage regulator, Hall voltage ^{ Multi Small Size option}
generator, small-signal amplifier, chopper stabilization, ^{ Low sensitivity drift in crossing of Temp. range}
Schmitt trigger, CMOS output driver. Advanced CMOS _{ Ultra Low power consumption at 5uA (Avg)}
wafer fabrication processing is used to take advantage of
 High ESD Protection, HMB > ±4KV( min )
low-voltage requirements, component matching, Very low
 Totem-pole output
input-offset errors, and small component geometries. This
device requires the presence of omni-polar magnetic fields
for operation.
Applications
The package type is in a Halogen Free version has been
verified by third party Lab.
