Frequently Asked Questions

What battery chemistries and maximum charge current does LTC1731EMS8-8.4#PBF support?

LTC1731EMS8-8.4#PBF supports Li-Ion, Li-Polymer, NiCd, and NiMH batteries with a programmable charge current up to 2000 mA, making it versatile for single-cell and 2-cell pack configurations in portable electronics.

For a 2-cell Li-Ion pack design, why is the 8.4 V fixed termination of LTC1731EMS8-8.4 significant?

The 8.4 V fixed termination voltage precisely matches the fully charged voltage of 2 series Li-Ion cells (each at 4.2 V), preventing overcharge and maximizing cycle life beyond 500 full charge cycles without requiring external voltage dividers.

How does LTC1731EMS8-8.4#PBF compare to switching charger ICs in noise-sensitive applications?

Unlike switching charger ICs that produce high-frequency switching noise above 100 kHz, LTC1731EMS8-8.4#PBF uses a linear topology that generates no switching artifacts, making it ideal for medical instruments and analog signal-chain boards that require sub-millivolt power supply ripple.

Is LTC1731EMS8-8.4#PBF available in lead-free packaging suitable for RoHS compliance?

Yes, the #PBF suffix denotes a RoHS-compliant lead-free solder finish (JESD-609 code e3), and the 8-pin MSOP tube packaging supports standard SMT assembly processes with a peak reflow temperature of 260°C for compliance with modern environmental regulations.
