AH3231Q, AH3232Q, AH3233Q AH3270Q, AH3271Q, AH3272Q TWO-WIRE AUTOMOTIVE HALL EFFECT UNIPOLAR / LATCH SWITCHES Description Pin Assignments The AH3231Q, AH3232Q, AH3233Q, AH3270Q, AH3271Q, and AH3272Q are high-voltage, high-sensitivity, two-wire, Hall-effect, Unipolar/Latch switch ICs with automotive-compliant AEC-Q100 qualification; designed for position and proximity sensing in automotive applications, such as seat and seatbelt buckle, transmission actuator, gear position, wiper, door/trunk closure, etc. (Top View) GND To support a wide range of demanding applications, the design is optimized to operate over a supply range of 2.7V to 27V. These features include a chopper-stabilized architecture and an internal bandgap regulator to provide temperature compensated supply for internal circuits. For robustness and protection, the device has built-in reverse blocking diode with a Zener clamp on the supply. SC59 (Type A1) The built-in thermal protection also shuts down the chip if temperature rises to an abnormal value. This will automatically restart the chip once the junction temperature drops below the safe value. (Top View) VDD For AH3231Q, AH3232Q, and AH3233Q 2-wire unipolar switches: when the flux density (south pole) exceeds BOP, the supply current state is turned on (low or high). The output is held until a magnetic flux density falls below BRP, causing output current to be turned off. For AH3270Q, AH3271Q, and AH3272Q 2-wire latch switches: when the magnetic flux density is larger than BOP, output current is turned on (high). The output state is held until a magnetic flux density reversal falls below BRP, causing output current to be turned off (low).

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 TPON(max), VDD slew rate > 1V/μs - IOFF - - Output jitter B≥3*BOPMAX 1000 successive square wave switching under 1KHz. - ±3.3 - μs TPON Notes: 7. 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. 8. VDD is the voltage between the VDD pin and the GND pin. 9. When power is initially turned on, VDD must be operated in the correct voltage range to guarantee proper magnetic field sampling, output supply current state level is valid after the start up time of 28μs from VDD higher than 2.7V. Guaranteed by design. 10. Time delayed from the magnetic threshold reached to the output rise or fall. 11. t > TPON and BRP
