AH3782

HIGH-VOLTAGE, HIGH-SENSITIVITY HALL EFFECT LATCH

WITH INTERNAL PULL-UP RESISTOR

Description

Pin Assignments

The AH3782 is a high-voltage, high-sensitivity Hall Effect latch IC

with internal pull-up resistor 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 has been 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 AH3782 provides a reliable solution over the whole

operating range. For robustness and protection, the device has a

Zener clamp on the supply. The output has an overcurrent limit and a

Zener clamp.

SC59 and SOT23

The internally pulled-up 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 part

marking surface 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).

2. GND

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 North

pole to the part marking side.
