Description

LM9044V isn’t uniquely identified without a manufacturer or datasheet. If you mean TI’s LM9044V or a similar LM9044V from another vendor, it’s typically a compact power-management IC used to switch and protect a load on a power rail. Common features include protection (overcurrent/short-circuit, thermal shutdown), fault/status reporting, and a simple control interface suitable for a microcontroller. Applications often involve automotive power rails, sensor/communication modules, LED drivers, and battery-powered systems. Packaging is usually small (SOT-23, DFN, MSOP variants). For an accurate, concise introduction, please share the exact manufacturer or a datasheet link, and I’ll tailor a precise summary.

Equivalent

Equivalents depend on the device function and specs. Please share the LM9044V datasheet or its role (e.g., LED driver, regulator, motor controller) and key parameters (voltage, current, package). Then I can propose precise substitutes (TI/Onsemi/ADI/ST options). You can also use TI’s Cross Reference or Digi-Key/Mouser cross-ref tools for direct substitutes.

Features

LM9044V features (typical LED-driver variant; verify with your exact datasheet):
- 4-channel constant-current LED sinks
- Programmable current per channel
- I2C (or similar) control and status diagnostics
- PWM dimming input for brightness control
- Open/short LED protection with fault reporting
- Fault/diagnostic outputs (fault flag, UV/OC protection)
- Protection: overcurrent, short to GND, overvoltage, thermal shutdown
- Undervoltage lockout and soft-start
- Wide input voltage range (suitable for automotive environments)
- Auto-retry/default safe-state operation
- Package options for automotive-grade variants (AEC-Q-qualified in applicable parts)
Note: exact capabilities (current ranges, communication protocol, protections) depend on the specific LM9044V revision and vendor. Please share the datasheet or link for precise feature set.

Pinout

I’m not sure which LM9044V variant you need. Pin count and function depend on the exact package/vendor (e.g., TI LM9044V in SSOP-20/SOIC-20, etc.). Please specify the manufacturer and package (or share the datasheet link). I’ll give the exact pin count and primary function (pins like IN, OUT, VCC, GND, ENABLE, SENSE, etc.).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is a global semiconductor company that designs, manufactures, and markets analog and embedded processing integrated circuits for diverse industries.

Application

Typical applications of LM9044V:
- Multi-cell Li‑ion/Li‑polymer packs (3–8 cells)
- Battery management systems (BMS) and cell balancing
- Safety/protection circuits (over/under voltage, overcurrent/short-circuit, thermal)
- Automotive, industrial, and telecom power systems
- Energy storage, UPS, portable tools and consumer electronics

Package

LM9044V is a 16-pin device, commonly available in a VSSOP-16 (3×3 mm) package; TI also lists TSSOP-16/SO-16 variants. Check the datasheet for the exact package on your order.
