Maxim Integrated claims to offer the industry’s first Li+ fuel gauge IC which has continuous internal self-discharge monitoring and protection. The MAX17320 series cell Li-ion fuel gauge IC extends run-time on multi-cell battery-powered products while also monitoring against self-discharge hazards. The pack-side fuel gauge and protector IC is for two to four series Lithium-ion (Li+) cells (2S-4S). It is part of a family of ICs equipped with Maxim Integrated’s patented ModelGauge m5 EZ algorithm that delivers 40 per cent more accurate state of charge (SOC) readings than competitive offerings, eliminating the need for battery characterisation for most common Li+ cells, claims the company. This fuel gauge is also claimed to offer the industry’s lowest quiescent current (IQ), which is 85 per cent lower than the nearest competitor and features SHA-256 authentication to safeguard systems from counterfeit batteries.
