AH3774
HIGH-VOLTAGE HIGH-SENSITIVITY HALL EFFECT LATCH
Description
The AH3774 is a high-voltage, high-sensitivity Hall Effect Latch IC
designed for commutation of brushless DC motor, 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 AH3774 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 over current 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 (Bop) the output is switched
on (pulled low). The output is held latched until magnetic flux density
reverses and becomes lower than the release point (Brp).
The magnetic operating and release polarity is opposite for SOT23
and SC59 packages. SOT23 and SIP-3 packages will require South
Pole to the part marking side to operate while SC59 will require South
Pole to the non-part marking side.
