What are the key features of LM3241TLX/NOPB?

  • Voltage-mode PWM battery charge controller enables precise single-cell Li-Ion charging with minimal external components
  • 2.7 V to 5.5 V input range supports USB 2.0 (5 V), USB 3.0, and Li-Ion pass-through charging scenarios
  • Ultra-compact 6-ball XBGA package (R-XBGA-B6) occupies minimal board area in thin portable devices
  • Single-function dedicated charge controller simplifies design versus multi-function PMICs for cost-sensitive single-cell applications
  • RoHS-compliant Pb-free (NOPB) and JESD-609 e1-coded for global regulatory compliance in consumer electronics

What is LM3241TLX/NOPB used for?

The LM3241TLX/NOPB is designed for single-cell Li-Ion battery charging in compact portable devices such as wireless earbuds, fitness trackers, and small IoT sensor nodes that charge from a USB 5 V source or a 2.7 V–5.5 V power adapter. Its voltage-mode PWM control ensures accurate constant-current and constant-voltage charging profiles required to safely charge a 4.2 V Li-Ion cell without overcharging. The 6-ball micro BGA package makes it the preferred choice for wearable and ultra-thin product designs where board space is at a premium and a dedicated charger IC is favored over a larger PMIC.

Frequently Asked Questions

What input voltage range does the LM3241TLX/NOPB support for Li-Ion battery charging?

The LM3241TLX/NOPB accepts an input voltage from 2.7 V to 5.5 V, making it directly compatible with USB 2.0 and USB 3.0 5 V VBUS charging sources. The 2.7 V lower bound also allows charging from nearly-depleted secondary cells or low-dropout adapters in multi-stage portable power systems.

How does the LM3241TLX/NOPB's 6-ball BGA package benefit space-constrained wearable designs?

The 6-ball XBGA package (JESD-30 code R-XBGA-B6) has a footprint of roughly 1.0 mm × 1.0 mm with 0.5 mm ball pitch, one of the smallest available for a functional battery charge controller. This allows it to fit beneath other components or in the dead zones of flexible PCBs in wireless earbuds, smart rings, and medical-grade skin-contact patches where every square millimeter of board area is budgeted.

Why use a dedicated LM3241TLX/NOPB charger rather than integrating charging into a multi-function PMIC?

For single-cell designs with a straightforward USB-to-Li-Ion charging requirement, a dedicated controller like LM3241TLX/NOPB costs less and has a smaller die area than a PMIC. Isolating the charger also simplifies power-path isolation: the charger handles 2.7 V–5.5 V input to 4.2 V Li-Ion output with its own voltage-mode PWM loop, while other rails are managed independently—reducing cross-coupling and simplifying fault isolation in the overall power architecture.

What control method does the LM3241TLX/NOPB use, and how does it affect charging accuracy for Li-Ion cells?

The LM3241TLX/NOPB uses voltage-mode pulse-width modulation (PWM) control. This method compares the battery voltage against an internal reference and adjusts duty cycle to regulate the charge voltage to within ±1% of the 4.2 V Li-Ion termination voltage, preventing overcharge—which can cause cell swelling or capacity degradation—while ensuring maximum charge energy is delivered within a safe 4.2 V ceiling.
