Advanced Battery protector to deliver the highest level of safety
Designers concerned about battery safety now have access to the most advanced battery protector with integrated fuel gauges from Maxim Integrated Products. The newest 1-cell, pack-side ICs in this portfolio are the MAX17301 and the MAX17311, which offer the most configurable settings for battery safety in the industry and uniquely allow fine tuning of voltage and current thresholds based on various temperature zones. These ICs also offer a first-of-its-kind secondary protection scheme in case the primary protection fails. This secondary protection scheme permanently disables the battery by overriding a secondary protector or blowing a fuse in severe fault conditions. All ICs in the family are equipped with Maxim’s patented ModelGauge™ m5 EZ algorithm that delivers a high state-of-charge (SOC) accuracy that on average offers 40 percent better accuracy than competitive offerings and eliminates the need for battery characterization.
These are the only 1-cell fuel gauges in the market that offer 2-level Li-ion protection, providing an additional layer of security in case the primary protector fails. These compact ICs are part of Maxim’s new portfolio of fuel-gauges that offer integrated protection capability that helps system makers meet new product safety standards such as IEC 62368-1/UL 62368-1. All ICs in the family offer unique low-state-based protectors as an alternative to simple low-voltage thresholds, that prevents nuisance tripping in the case of short duration voltage dips due to pulse loads on the battery. As with the rest of the portfolio, these devices also provide the highest SOC accuracy without requiring battery characterization, eliminating several weeks of time required for sending a battery to a lab for characterization and analysis. Furthermore, the portfolio offers the market’s lowest IQ, extending battery shelf life for compact electronics.
