DRV5011ADDMRR

The DRV5011ADD/MRR is TI’s Hall-effect latch switch. It senses a magnetic field and provides a digital output that toggles when the field crosses a set threshold and remains latched until the opposite polarity threshold is reached, making it suitable for non-contact position sensing and magnetic switches.
Key points:
- Unipolar Hall sensor with latched output and hysteresis.
- Wide supply range (roughly 2.7–5.5 V) with low current.
- Output is a logic signal; packaged in compact MR/R suffix options.
- Ideal for door/magnet sensing, rotary encoders, end-stop switches, and other position-sensing tasks.
- Includes protection features; refer to the datasheet for exact trip/release values and electrical characteristics.
Note: The MR/R suffix indicates the package; always check the TI datasheet for your exact variant and specifications.

Equivalent parts for TI DRV5011ADDMRR (unipolar Hall-effect latch) from other vendors include:
- Allegro Microsystems: A1321, A1322, A1324
- Melexis: MLX9036x/MLX90364 family
- Honeywell: SS49/SS495 series
Note: verify supply voltage, output type (latched vs. standard), sensitivity, and package. Use TI cross-reference to confirm exact electrical/mechanical compatibility.

Here are the typical features of TI DRV5011ADD(MRR) (Hall-effect latch sensor):
- Unipolar Hall-effect latch with digital output
- Latched switching: defined ON/OFF thresholds (BOP and BRP) to reduce chatter
- Wide operating supply voltage range
- Low power consumption (low quiescent current)
- Output type: open-drain (requires external pull-up) for simple interfacing
- Fast magnetic response with built-in hysteresis
- Protection features: ESD protection and fault protection
- Robust operation over a wide temperature range
- Small package with standard RoHS-compliant, automotive/industrial grade options (MRR/ADD variants indicate packaging)
- No mechanical contact; immune to wear-and-tear, suitable for position/speed sensing
Note: Exact electrical specs (thresholds, current, voltage range, temp range) vary by variant; please consult the latest TI datasheet for precise figures.

- Pin count: 8 pins (MSOP/8-pin package in the MRR code).
- Function: TI DRV5011ADDMRR is a Hall-effect unipolar switch with a digital output. It detects a magnetic field crossing its trip threshold and outputs a corresponding logic level (typically a push-pull output) to indicate magnet presence.

Manufacturer: Texas Instruments (TI).
What kind of company: TI is a global American semiconductor company that designs and manufactures analog, embedded processing, and other integrated circuits.

Applications of DRV5011ADDMRR (a digital Hall-effect latch):
