TWO-WIRE AUTOMOTIVE HALL SWITCHES INTEGRATED SELF-DIAGNOSTICS

Description

Pin Assignments

The DIODES™ AH3241Q-AH3244Q/AH3280Q-AH3282Q are high

voltage, high sensitivity, two-wire Hall Effect Unipolar/Latch switch ICs

with integrated self-diagnostics and 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.

To support a wide range of demanding applications, the AH3241Q-

AH3244Q/AH3280Q-AH3282Q are 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.

VDD

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.

GND

For AH3241Q, AH3242Q, AH3243Q, and AH3244Q 2-wire unipolar

switches: when the flux density (south pole) exceeds B_OP, the supply

current state is turned on (low or high). The output is held until a

magnetic flux density falls below B_RP, causing output current to be

turned off.

VDD

SIP-3

For AH3280Q, AH3281Q, and AH3282Q 2-wire latch switches: when

the magnetic flux density is larger than B_OP, output current is turned

on (high). The output state is held until a magnetic flux density

reversal falls below B_RP, causing output current to be turned off (low).
