The LTC4079EDD#PBF is a high voltage linear charger from Analog Devices, suitable for various battery chemistries including Li-Ion, LiFePO4, Lead-Acid, and NiMH, supporting battery stacks up to 60V. It features an adjustable charge current ranging from 10mA to 250mA, set by an external resistor, and an adjustable battery charge voltage determined by an external resistor divider.
This charger integrates a power device, current sensing, and reverse current protection, minimizing external component count. Thermal regulation ensures maximum charge current without overheating, while input voltage regulation is beneficial for energy harvesting applications. Additional features include temperature-qualified charging, bad battery detection, automatic recharge with low battery drain in standby, and an adjustable safety timer. The device is housed in a compact, thermally enhanced 10-lead (3mm x 3mm) DFN package, making it suitable for embedded automotive and industrial applications.
Key electrical specifications include a wide input voltage range of 2.7V to 60V and an adjustable battery voltage from 1.2V to 60V. The constant voltage feedback offers ±0.5% accuracy. The low quiescent current while charging is 4µA, and battery drain when shutdown or charged is less than 0.01µA. The device also includes an NTC thermistor input for temperature-qualified charging and an open-drain CHRG status output.
