Product details

LiFePO4 charging with 60 V input headroom

The LTC4000IGN-1#PBF is a constant-current, programmable charger IC from the PowerPath™ series, designed specifically for Lithium Iron Phosphate (LiFePO4) battery chemistries. 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.

Frequently asked questions

Will LTC4000IGN-1#PBF drop into a board designed for LTC4000IGN#PBF?

The LTC4000IGN-1#PBF shares the same 28-SSOP package, 60 V supply voltage, LiFePO4 chemistry target, and reverse-current fault protection as the LTC4000IGN#PBF. The key difference is the -1 suffix, which typically indicates a variant in the charge-current programming range or timer configuration — confirm the specific charge algorithm and timer settings in the datasheet before assuming a drop-in replacement.

What compliance documentation does Analog Devices provide for LTC4000IGN-1#PBF?

The LTC4000IGN-1#PBF is ROHS3 Compliant per Analog Devices' lifecycle record. Standard compliance documentation includes the RoHS declaration of conformity and the material declaration sheet; these are available through the distributor upon request.
