Description

The LV8044LP-TLM-E is a dedicated LED driver IC used to power LED strings with constant current, typically for backlighting and general lighting. It is a multi-channel, high-efficiency device that regulates current to the LEDs, often from a higher-voltage supply, and supports dimming control (PWM or analog) via a DIM/CTRL input. External sense or feedback components set the LED current, and the device includes protections such as open/short LED, overcurrent, and thermal shutdown. The “TLM-E” suffix indicates the package variant (leadless, tape-and-reel/EMI version, lead-free). Common applications include LCD backlights for TVs/monitors, signage, and automotive lighting. For exact electrical specifications (current per channel, input range, dimming range, number of channels) refer to the official datasheet from the manufacturer.

Features

LV8044LP-TLM-E is a 4-channel LED driver IC. Key features (typical):
- Four constant-current outputs
- Per-channel current adjustable via external resistors
- Dimming via PWM and/or analog control
- Protections: LED open/short, overcurrent, overvoltage, and thermal shutdown
- High efficiency with an integrated regulator/drive circuitry
- Suitable for compact LED backlighting, signage, etc.
- Small TLM-E package with tape-and-reel option for surface-mount assembly
Note: exact electrical specs and pinout can vary by revision; consult the official datasheet for precise values and application guidance.

Package

The LV8044LP-TLM-E uses a TLM package—Tape-Molded Leadframe (leadframe molded).

Pinout

Pin count: 28 pins (LP-TLM-E package).
Function: A dual, 2-phase stepper motor driver with current regulation. It drives a bipolar motor via four motor-output pins (two windings) and accepts logic inputs such as STEP and DIR (plus ENABLE, RESET/SLEEP, and microstep selection if provided). Requires a logic supply (VCC) and a motor supply (VM), with current set by a reference input (VREF). For exact pinout and detailed capabilities, see the LV8044LP-TLM-E datasheet.

Manufacturer

Would you like me to search the web for the exact manufacturer? I can fetch the datasheet and briefly describe the company.

Application

LV8044LP-TLM-E is a two‑phase stepper-motor driver IC. Typical applications: precise motor control in printers, scanners, and copiers; 3D printers and small CNC machines; robotics and automated equipment; industrial automation and lab instruments requiring accurate positioning and speed control.

Equivalent

LV8044LP-TLM-E is a 2-phase microstepping stepper driver with translator. Direct cross-references vary by package and current rating, but common equivalents include:
- Allegro A4988 / A4983
- TI DRV8825 (also DRV8880)
- ST L6470 / L6480
- Trinamic TMC2100 / TMC2130 / TMC2208
Note: verify pinout, current, and voltage specs; use a distributor cross-reference tool for exact matches.
