PST443 is
a switched Hall-Effect
IC, suitable for contactless
switching applications.
The device includes
an on-chip Hall voltage
generator for magnetic sensing,
an amplifier that amplifies the Hall
voltage, a Schmitt trigger to provide switching
hysteresis for noise
rejection, and an
open-collector output.
The bandgap regulator
allows a wide
operating voltage range.
PST443 is rated over from -20°C
to 85°C or -40°C
to 150°C operating temperature
range and from 3.8V
to 30V operating voltage
range. PST443 are
capable of continuous
20mA sinking
out current or as high
as 50mA maximum pulse current.
