Overview

Description

A4939KLPTR-5-T is an Allegro Microsystems device from the A4939 family, a Hall-effect sensor/driver IC used for rotor-position sensing and motor commutation in BLDC motors (and related automotive/industrial applications). The “KLPTR” indicates a leadless KLP packaging with tape‑and‑reel shipping. The IC typically integrates a Hall element with signal conditioning and a digital output (with protection features) powered from a 3–24 V supply. For exact electrical specs, pinout, and applications, consult the official datasheet.

Package

KLP = Plastic Leadframe Package (leadframe). A4939KLPTR-5-T uses Allegro’s KLP plastic leadframe package with Tape & Reel packaging.

Pinout

- Pin count: 28 pins
- Function: Dual DMOS full-bridge motor driver (drives two DC motors or one bipolar stepper motor) with two independent H-bridges, current regulation, protections (OC/thermal), and control inputs (direction/step, enable, etc.).

Manufacturer

Manufacturer: Allegro MicroSystems.
Allegro MicroSystems is a semiconductor company that designs and manufactures magnetic-sensing ICs and motor-control ICs, including Hall-effect sensors for automotive and industrial applications.

Application

- BLDC and stepper motor drive/controllers
- Robotics and automation (robot arms, conveyors)
- Automotive actuators (power seats, windows, mirrors)
- Printers, CNC machines, and other industrial equipment
- Consumer electronics requiring precise motor control and PWM current regulation
