MAX17300-MAX17303/ 1-Cell ModelGauge m5 EZ Fuel Gauge with MAX17310-MAX17313 Protector, Internal Self-Discharge Detection and SHA-256 Authentication General Description Benefits and Features The MAX17300-MAX17303/ MAX17310-MAX17313 is a Battery Health + Programmable Safety/Protection 24A I stand-alone pack-side fuel gauge IC with protec- Overvoltage (Temperature Dependent) Q tor, optional battery internal self-discharge detection and Overcharge Current optional SHA-256 authentication for 1-cell lithium-ion/poly- Over/Undertemperature mer batteries. Battery Internal Self-Discharge Detection (MAX17300/10 Only) The IC monitors the voltage, current, temperature, and Ideal Diode Discharge During Charge Fault state of the battery to provide against over/undervoltage, Charging Prescriptions (JEITA) overcurrent, short-circuit, over/undertemperature, over- Zero-Volt Charging Option charge, and internal self-discharge conditions using exter- Undervoltage + SmartEmpty nal high-side N-FETs, and provides charging prescription Overdischarge/Short-Circuit to ensure that the lithium-ion/polymer battery operates un- der safe conditions prolonging the life of the battery. Nonvolatile Memory for Stand-Alone Operation History Logging, User Data (122 Bytes) To prevent battery pack cloning, the IC integrates SHA-256 authentication with a 160-bit secret key. Each IC Low Quiescent Current incorporates a unique 64-bit ID. FETs Enabled: 24A Active, 18A Hibernate FETs Disabled: 5A Ship, 0.5A/0.02A DeepShip The fuel gauge uses ModelGauge m5 algorithm that com- bines the short-term accuracy and linearity of a coulomb Parallel Battery Management (MAX17300/10 Only) counter with the long-term stability of a voltage-based fuel Pushbutton WakeupEliminates System gauge to provide industry-leading fuel-gauge accuracy.
