The DRV5023FAEDBZRQ1 is a unipolar Hall-effect switch from Texas Instruments, part of the Automotive, AEC-Q100 qualified series. It is packaged in a 3-pin SOT-23 surface-mount package and supplied on tape and reel. This south-pole-activated unipolar switch has a typical magnetic operate point of 6 mT and a release point of 0.5 mT, giving 5.5 mT of hysteresis. The open-drain output sinks up to 30 mA, and the device operates from a 2.7 V supply while drawing 2.7 mA switching current.
AEC-Q100 qualification and temperature range
This covers under-hood and chassis-mounted sensor applications where the silicon sees the engine compartment or transmission bay thermal profile. The temperature-compensated design maintains consistent magnetic trip points across the full temperature range, avoiding false triggers or missed detections as the Hall plate sensitivity drifts with temperature.
Supply and output characteristics
The 2.7 mA supply current is low enough for always-on sensing in ignition-off applications, though not as low as a micropower Hall switch. The open-drain output requires a pull-up resistor to the logic supply. The 30 mA output current capability is sufficient to drive a PLC digital input or a logic gate directly, but a series resistor is needed if driving a relay coil or LED.
No official second-source or pin-compatible cross-reference is recorded for this exact order code.
