AH3772

HIGH-VOLTAGE, HIGH-SENSITIVITY HALL EFFECT LATCH

Description

Pin Assignments

The AH3772 is a high-voltage, high-sensitivity Hall Effect latch IC

designed for commutation of brushless DC motors, flow meters,

linear encoders, and position sensors in industrial and consumer

home appliances 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 AH3772

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).
