Fuel gauges offer highest level of battery protection

Maxim's MAX17301 and the MAX17311 1-cell fuel gauge devices allow fine tuning of voltage and current thresholds based on various temperature zones with a low quiescent current of 24μA Maxim Integrated Products has developed a 1-cell battery fuel gauge that can provide counterfeit and...

Fuel-gauge ICs help prevent battery clones

Maxim’s family of ModelGauge m5 standalone fuel gauges provides SHA-256 authentication with a 160-bit secret key to make it harder to clone battery packs. The ICs also implement the ModelGauge m5 algorithm, which converts raw measurements of battery voltage, current, and temperature...

Battery-pack fuel gauge with SHA-256 authentication prevents pack cloning

Implementing pack-side battery gauges in portable devices is easier and more secure, Maxim asserts, with its ModelGauge m5 portfolio of MAX17201/MAX17205 and MAX17211/MAX17215. Fuel gauging can be difficult because battery voltage varies with temperature and load, while...
