AH3777
HIGH-VOLTGAE LOW-SENSITIVITY HALL EFFECT LATCH
Description
The AH3777 is a high voltage, low sensitivity Hall effect latch IC
designed for commutation of brushless DC motors, flow meters,
linear encoders and position sensors in industrial and consumer
home appliance and personal care applications. To support a wide
range of demanding applications, the design is optimized to operate
over the supply range of 3.0V to 28V. With chopper-stabilized
architecture and an internal bandgap regulator to provide
temperature compensated supply for internal circuits, the AH3777
provides a reliable solution over the whole operating range. For
robustness and protection, the device has a reverse blocking diode
with a Zener clamp on the supply. The output has an overcurrent limit
and a Zener clamp.
The single, open-drain output can be switched on with South pole of
sufficient strength and switched off with North pole of sufficient
strength. When the magnetic flux density (B) perpendicular to the
package is larger than the operate point (B
OP
) the output is switched
on (pulled low). The output is held latched until magnetic flux density
reverses and becomes lower than the release point (B
RP
).
