AEC-Q100 unipolar Hall switch for 150°C ambient
The Texas Instruments DRV5023AJELPGQ1 is a unipolar Hall-effect switch from the DRV5023 series, qualified to AEC-Q100 for automotive applications. It switches on when a south-pole magnetic field exceeds 12 mT (typical operate point) and releases at 1 mT (typical), providing a clean digital output through an open-drain stage. The temperature-compensated design keeps the operate and release points stable across this band, so the error budget for the system's magnetic threshold does not widen with temperature.
2.7 V supply, 2.7 mA draw — power budget fit
The device operates from a 2.7 V supply rail, drawing 2.7 mA typical switching current. The 30 mA maximum output current drives a downstream pull-up resistor or PLC input without an external buffer. Stack this current against the module's sleep budget: at 2.7 mA the sensor's draw is comparable to a single LED indicator, not a power-stage load.
No end-of-life notice or last-time-buy window is in effect. For new designs, the AEC-Q100 qualification and 150°C rating make this a straightforward choice for automotive position or speed sensing. No second-source or pin-compatible alternative is recorded in the Texas Instruments DRV5023 family — the part is single-sourced to the original manufacturer.
