LM3658SDX-B/NOPB Description

Short technical summary and product information.

The LM3658SDX-B/NOPB from Texas Instruments is a versatile single-chip charger IC engineered for handheld and portable applications. It is designed to safely charge and maintain single-cell Lithium-Ion or Polymer batteries.

 

This IC supports charging from either an AC wall adapter or a USB power source, with automatic source selection. It offers a maximum charge current of 1A via AC adapter and pin-selectable USB charge currents of 100mA or 500mA. The battery charge voltage is regulated to 4.2V. The device operates within an input voltage range of 4.5V to 6V, with an absolute maximum of 6.5V.

 

Key features include continuous battery temperature monitoring, built-in safety timers, over-current and over-temperature protection, and near-depleted battery pre-conditioning. It also includes a sleep mode with ultra-low quiescent current and a maintenance mode with automatic recharge. The IC is housed in a thermally enhanced 10-WSON (3x3 mm) package, suitable for surface mounting.

 

The operating temperature range is -40°C to 85°C. The control interface is standalone and RC-settleable, with a linear control topology. On-board Kelvin-sensing provides ±0.35% termination accuracy.
