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 (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).
