概述

Description

A1330LLETR-DD-T is Allegro Microsystems’ Hall-effect switch IC in a tape-and-reel package. It belongs to the A1330 family and is a latched (bistable) Hall sensor that detects magnetic flux and provides a digital output. When a magnetic field crosses its predefined threshold, the output changes state and remains latched until the field reverses beyond the hysteresis point. This makes it suitable for non-contact position sensing, motor commutation, speed sensing, and proximity sensing in automotive and industrial applications.
Key points:
- Latched Hall-effect switch with digital output
- Non-contact magnetic field sensing
- Packaged for automated assembly (tape-and-reel)
- RoHS-compliant variant indicated by the suffix
For exact electrical specs, thresholds, hysteresis, pinout, and operating voltage range, consult the latest A1330LLE datasheet and the packaging/documentation for the DD-T variant.

Package

Leadless Leadframe Package (LLP), 8-pin.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC-8)
- Function: Hall-effect latch/switch sensor with a push-pull digital output (unipolar). It detects a magnetic field and changes its output state (latches on/off around the threshold) accordingly.

Manufacturer

- Manufacturer: Allegro MicroSystems, Inc.
- Company type: A semiconductor company specializing in Hall-effect magnetic sensors and sensor ICs for automotive, industrial, and consumer electronics.

Application

Applications: non-contact magnetic sensing for position and speed; rotary encoders and motor-commutation; automotive sensing (wheel-speed sensing, door/hood/seat position); industrial automation (limit/proximity sensing, safety interlocks, robotics); consumer electronics and appliances (magnet-detection for devices).
