Visão Geral

Description

The LV8044LP-TLM-E is a dedicated two‑phase stepper motor driver IC intended to drive small bipolar steppers from a microcontroller. It provides current‑regulated outputs to the two windings, controlled via simple STEP/DIR (with ENABLE/SLEEP options on many variants). The device includes protections such as overcurrent, overtemperature, and undervoltage lockout, plus standby modes for power saving. The -TLM-E suffix indicates Tape & Reel packaging for automated assembly. Typical applications include printers, scanners, small robotics, and compact actuators. For exact electrical specs, timing diagrams, pinout, current settings, and recommended circuitry, consult the official LV8044LP-TLM-E datasheet from the manufacturer.

Pinout

Pin count: 16 pins (SSOP-16/LQFP-16 package variants).
Function: LV8044LP-TLM-E is a dual H-bridge stepper motor driver with built‑in current regulation. It drives a two‑phase bipolar stepper motor via four control inputs (IN1–IN4 or STEP/DIR style typical) and provides motor outputs (two bridge pairs) from VM (motor supply) and logic VCC, with ground and control pins (EN/SLP/RST, ISET, etc.) for enabling, sleeping, resetting, and setting current.

Manufacturer

- Manufacturer: Renesas Electronics Corporation (formerly part of NEC).
- What kind of company: A Japanese multinational semiconductor company that designs and manufactures microcontrollers, analog and power ICs, SoCs, and automotive-grade semiconductor solutions for automotive, industrial, and consumer markets.

Application

LV8044LP-TLM-E is a dual-phase stepper motor driver IC for precise control of small stepper motors. Common application areas include:
- Printers, scanners, copiers (paper handling, carriage drives)
- Office automation devices (cash registers, ticketing, labelers)
- Small robotics and automation systems
- Medical and laboratory instruments requiring precise positioning
- Consumer electronics with micropositioning/actuation
- Hobbyist CNC, engraving, and 3D-printer projects

Package

LQFP (low-profile quad-flat package), 48-pin, RoHS-compliant (lead-free).
