MAX17301–MAX17303/MAX17311–MAX17313 Fuel Gauges

Analog Devices MAX17301–MAX17303/MAX17311–MAX17313 Fuel Gauges offer a protector and optional SHA-256 authentication for 1-cell lithium-ion/polymer batteries. These devices monitor the battery's voltage, current, and temperature, allowing over/under voltage, overcurrent, short-circuit, over/under temperature, and overcharge protection. Using external high-side N-FETs, the protection features ensure that the lithium-ion/polymer battery operates under safe conditions, prolonging the battery's life.
