AH3769Q

HIGH-VOLTAGE, LOW-SENSITIVITY

AUTOMOTIVE HALL-EFFECT LATCH

Description

Pin Assignments

The AH3769Q is an AEC-Q100 qualified high-voltage, low-sensitivity

Hall-Effect latch IC designed for brushless DC-motor commutation,

speed measurement, angular or linear encoders and position sensors

in automotive 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 AH3769Q 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.

1 V_DD

GND 2

SOT23

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).
