AH3777

HIGH-VOLTGAE LOW-SENSITIVITY HALL EFFECT LATCH

Description

Pin Assignments

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).
