DRV5033AJEDBZRQ1 Automotive-Grade Omnipolar Hall Effect Sensor (SOT-23)

Build ultra-reliable, dirt-proof mechanical limits and position sensors with the DRV5033AJEDBZRQ1 omnipolar Hall effect switch. Unlike traditional optical limit switches that can easily be blocked by dust, mud, or moisture, this magnetic sensor provides flawless contactless detection. Because it is "omnipolar," it responds to both the North and South poles of a magnet. This makes mounting and calibrating magnets on your custom CNC machines, drone retractable landing gears, or robotic arms incredibly easy, as you don’t have to worry about magnetic orientation.

Carrying the "Q1" designation, this Texas Instruments chip is strictly AEC-Q100 automotive-qualified. This means it offers bulletproof reliability, featuring built-in reverse battery protection and the ability to withstand severe voltage transients. Operating on a massive voltage range from 2.7V all the way up to 38V, it easily integrates directly into high-voltage systems (like 6S or 8S LiPo setups) without needing a dedicated step-down regulator. Housed in a standard SOT-23 package, it features an open-drain output that seamlessly interfaces with both 3.3V and 5V microcontrollers.

Key Features:

• Omnipolar Operation: Activates in the presence of either a North or South magnetic pole, drastically simplifying magnet installation and mechanical design.

• Automotive Grade (AEC-Q100): Built to withstand extreme temperatures and electrical stress, making it perfect for heavy-duty robotics and outdoor drones.

• Wide Voltage Range: Operates effortlessly from 2.7V to 38V, allowing direct connection to high-voltage battery packs.

• Robust Protections: Integrates reverse-polarity protection (up to -22V) and load dump protection for maximum circuit safety.
