LTC4015IUHF in Linear Tech / ADI LT Series Family
The LTC4015IUHF is a high-performance, multi-chemistry buck battery charger controller designed by Analog Devices (Linear Technology). It is capable of charging Lead-Acid, Li-Ion, and LiFePO4 battery chemistries with integrated telemetry. Operating over a wide 4.5V to 35V input range, it provides high-efficiency power management for complex multi-cell systems. The device features an onboard 14-bit ADC for monitoring battery and system parameters, making it a critical component for intelligent power systems requiring precise state-of-health and state-of-charge tracking.
Variants in This Sub-Family
Variants within the LTC4015 series primarily differentiate based on their operating temperature ranges, with the 'I' grade (LTC4015IUHF) rated for industrial use between -40°C and 125°C. Packaging is typically the 38-lead 5mm x 7mm QFN. Part number suffixes like #PBF denote lead-free, RoHS-compliant finishes, while #TRPBF indicates tape and reel packaging for high-volume automated assembly. The underlying silicon architecture remains consistent across these thermal and logistics-focused variations.
