Overview

Description

A4919GLPTR-T is a part number from Allegro MicroSystems (A49xx family). The suffixes (GLPTR-T) indicate packaging and handling details (eg, tape & reel packaging; RoHS/lead-free, etc.). The exact function depends on the specific variant within the A49xx family, which covers different magnetic-sensing and motor-control ICs.
Two common interpretations:
- Hall-effect position/speed sensor variant: detects a magnetic field and provides a digital or latched output for motor commutation or position sensing.
- Motor-driver/translator variant: drives or translates signals for brushless DC motor control (microstep control, current regulation, etc.).
Key idea: check the exact datasheet to confirm whether it’s a Hall-effect sensor or a motor-driver IC, and note typical specs (supply voltage, output type, sensitivity, magnetic operating range, package). If you share the datasheet or clarify which function you need (sensor vs. driver), I can give a precise, concise introduction with the key specs.

Features

A4919GLPTR-T is a dual-channel bipolar stepper motor driver with integrated power MOSFETs. Key features include:
- Two full-bridge outputs for bipolar stepper motors
- PWM current regulation with selectable decay modes
- Adjustable current limit via reference (Imax set by sense resistor)
- Step and Direction inputs with Enable; Sleep/Reset option
- Microstepping support (full-step to high-resolution steps)
- Built-in protections: overcurrent, overtemperature, undervoltage
- Fault/Status reporting pins for diagnostics
- Wide motor supply (VMOT) range and separate logic supply
- Packaging: GLP (Green Leadframe Plastic) with Tape & Reel (TR) option
Note: Exact voltage ranges and microstep details are specified in the datasheet; refer to it for precise numbers.

Package

It’s in a GLP package (Green Plastic Leaded). The suffix -T indicates Tape & Reel packaging.

Pinout

- Pin count: 28 pins (28-pin package).
- Function: Allegro A4919GLPTR-T is a bipolar stepper motor driver with translator (microstepping). It drives two motor windings via two H-bridges, accepts control inputs (STEP, DIR, ENABLE, RESET/SLEEP, MS1–MS3) and provides FAULT/STATUS outputs, with separate VMOT and logic supplies and current-regulation for the motor.

Manufacturer

Manufacturer: Allegro MicroSystems, LLC.
What kind of company: A global designer and manufacturer of magnetic-sensing ICs and motor-control ICs, including Hall-effect sensors, current sensors, and motor drivers for automotive and industrial applications.

Application

A4919GLPTR-T is an Allegro motor-drive IC used for controlling small DC and bipolar stepper motors. Typical applications include robotics and automation actuators, printers/scanners and other office equipment, 3D printers, automotive actuators (power windows/mirrors/seats), consumer appliances, and general industrial equipment requiring compact, efficient motor drive with current regulation.
