概要

Description

LM9044VX/NOPB is TI’s low‑power single‑cell Li‑ion battery gas gauge IC (LM904x family). It monitors pack voltage, current (via an external sense resistor), and temperature (NTC), and performs coulomb‑counting to estimate state of charge (SOC). An I2C‑compatible interface lets a host MCU read SOC, V, I, T, and status, and configure thresholds/calibration. It provides protection features (over/under voltage, overcurrent/short‑circuit, battery presence) and supports wake/sleep for low power. The NOPB suffix means Pb‑free packaging, and VX denotes a specific package variant. External components required are a sense resistor and an optional NTC thermistor. Applications include single‑cell Li‑ion/Li‑poly battery packs in mobile devices, tablets, wearables, power tools, USB power banks, and other portable electronics. A microcontroller or host is used to drive the I2C bus and integrate SOC into system power management.

Package

I don’t have that package detail memorized. May I look up the LM9044VX/NOPB datasheet online and confirm the exact package type for you?

Application

Typical applications for LM9044VX/NOPB include:
- Automotive power management and protection (battery sensing, load switching)
- Industrial and consumer electronics needing precise analog front-end
- Battery-powered devices (voltage regulation, current monitoring)
- Motor control and power electronics (current/voltage sensing, feedback)
- Sensor-conditioning front-ends in measurement systems

Equivalent

I don’t have enough detail to identify equivalents. Please confirm the device type (voltage regulator, comparator, transistor, etc.), key specs (output voltage/current, fixed/adjustable, dropout, package), or a datasheet link — with that I can list direct, pin‑ and spec‑compatible substitutes.
