Its 60 V maximum supply voltage means it can regulate charging from a 48 V industrial bus or a multi-cell Li-Ion stack without an external step-down stage — the internal FETs and control loop handle the full rail-to-cell differential. ## Active production and sourcing posture Analog Devices lists the LTC4000IGN-1#PBF as Active in its lifecycle status, and it carries ROHS3 compliance. ## Fault protection and programmable timer The IC includes reverse-current fault protection, which blocks battery discharge back through the charger when the input supply is removed or shorted — a critical safeguard in multi-source power architectures. A programmable timer feature allows the charge termination period to be set with an external capacitor, giving the designer control over the safety timeout independent of the charge current programming resistor. ## Industrial temperature grade The wide junction-temperature range means the charge-current programming must be derated above 85°C ambient to stay within the package's thermal impedance limits — the datasheet's SOA curves provide the derating factor.","metaTitle":"LTC4000IGN-1#PBF LiFePO4 Battery Charger IC, 60V, 28-SSOP","metaDescription":"Active Analog Devices LTC4000IGN-1#PBF LiFePO4 battery charger IC, 60V max supply, 28-SSOP package.
