Descripción general

Description

DRV5032FADMRR is a Texas Instruments Hall‑effect sensor that functions as a unipolar digital switch. It detects magnetic polarity and produces a logic-level output when the field crosses a defined threshold, with built-in hysteresis to prevent chatter. The FADMRR suffix indicates a specific small surface‑mount package variant.
Key points:
- Type: Hall-effect switch (digital output)
- Output: logic level (open‑drain or push‑pull variants depending on version)
- Features: low quiescent current, fast response, and protection (ESD/short‑circuit as applicable)
- Package: compact 3‑pin SMT package
- Applications: position and speed sensing, gear/magnet sensing, motor commutation, door/limit sensing
For exact electrical specs (thresholds, hysteresis, supply range, and output type) consult the DRV5032FADMRR datasheet and TI product page.

Features

Here are the typical features of the DRV5032FADMRR (Hall-effect switch):
- Hall-effect, unipolar latch switch
- Wide operating voltage: 3 to 24 V
- Latched output (magnet sets/releases the output)
- Digital output compatible with TTL/CMOS levels
- Low power consumption
- Fast response/release times
- Integrated protection features (ESD protection; robust operation over temperature)
- Wide operating temperature range (-40°C to +125°C)
- Small surface-mount package (MRR) with reel/tape packaging
Note: exact threshold values, output type (push-pull vs. open-drain), and pinout are specified in the datasheet.

Package

The DRV5032FADMRR is supplied in a 3-pin SOT-23 (TO-236-3) package and typically shipped on tape-and-reel.

Pinout

- Pin count: 3 (SOT‑23 package).
- Pin functions: VCC — power supply input; GND — ground return; OUT — digital Hall‑effect switch output (magnetic sensor output that changes state when the magnetic field crosses the device threshold).

Manufacturer

Manufacturer: Texas Instruments (TI).
Company type: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits for global electronics markets.

Application

- Non-contact magnetic switches and proximity sensing (doors/windows, lids)
- Magnetic position sensing for encoders (gear-tooth, rotary/linear position)
- Motor/actuator feedback (BLDC commutation, speed/position sensing)
- Robotics and automation sensing
- Limit-switch replacement in machinery
- Presence/absence detection in consumer electronics

Equivalent

Functionally equivalent digital unipolar Hall-effect switches include TI DRV5033/DRV5034 (same family), Allegro A3144/A3213, and Melexis US5881. Other vendors (Honeywell, Diodes Inc., Infineon) also offer comparable Hall switches—always verify VCC range, switching thresholds, output type (push‑pull vs open‑collector) and package before substituting.
