Frequently Asked Questions

What is the maximum charge current of the LM3658SD/NOPB?

The LM3658SD/NOPB supports a programmable maximum charge current of up to 500mA, set by an external resistor connected to the ISET pin. When powered from a USB port in 100mA mode, the charge current is automatically limited to 90mA to comply with USB specifications.

What package does the LM3658SD/NOPB come in, and what are its dimensions?

The LM3658SD/NOPB is housed in a WSON-10 (Wettable Flank Quad Flat No-Lead) package measuring 3mm x 3mm with a 0.5mm pitch. The compact footprint is ideal for space-constrained portable designs such as wearables and handheld devices.

Can the LM3658SD/NOPB power the system load while charging the battery?

Yes. The LM3658SD/NOPB features integrated power path management that allows it to simultaneously power the system load from the input supply while charging the battery. This prevents the system from losing power during battery charging and is especially useful in designs where the battery may be deeply discharged.

What are common alternatives or pin-compatible substitutes for the LM3658SD/NOPB?

Common alternatives include the Texas Instruments BQ24040 (single-input USB charger with similar current range), and the MCP73831 from Microchip (simpler single-cell Li-Ion charger). For dual-input designs with higher current, the TI BQ24090 is a functional upgrade. Verify pin compatibility and feature requirements against your target design before substituting.

Is the LM3658SD/NOPB RoHS compliant and what is its operating temperature range?

Yes, the LM3658SD/NOPB is RoHS compliant and lead-free. It is rated for an industrial operating temperature range of -40°C to +85°C, making it suitable for both consumer and light industrial portable applications.
