AH3762Q
HIGH-VOLTAGE, HIGH-SENSITIVITY
AUTOMOTIVE HALL EFFECT LATCH
PRELIMINARY - CONFIDENTIAL
Description
Pin Assignments
The AH3762Q is an AEC-Q100 qualified high-voltage, high-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 AH3762Q 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.

3 OUTPUT
GND 2
1 VDD
SC59 and 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 (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).

2. GND
1. VDD
The magnetic operating and release polarity is opposite for SOT23
and SC59 packages. SOT23 and SIP-3 (Ammo Pack), SIP-3 (Bulk
Pack) packages will require south pole to the part marking side to
operate while SC59 will require south pole to the non part-marking
side.

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.
2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and
Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain Bop (Note 10 )

7. When power is initially turned on, VDD must be within its correct operating range (3.0V to 28V) to guarantee the output sampling. The output state is valid
after the start-up time of 10s typical from the operating voltage reaching 3V.
8. Typical values are defined at TA = +25°C, VDD = 12V. Maximum and minimum values over the operating temperature range are not tested in production
but guaranteed by design, process control and characterization.
9. Guaranteed by design, process control and characterization. Not tested in production.
10. The device will limit the output current IOUT to current limit of IOCL.
