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.
