Produktöversikt

The LTC4015EUHF#PBF is a multi-chemistry buck battery charger controller with digital telemetry system in 38 pin QFN package. This complete high efficiency synchronous buck controller/charger has pin selectable, chemistry specific charging and termination algorithms. The LTC4015 can charge Li-ion/polymer, LiFePO4 or lead acid batteries. Battery charge voltage is pin selectable and I2C adjustable. Input current limit and charge current can be accurately programmed with sense resistors and can be individually adjusted via I2C port. A digital telemetry system monitors all system power parameters. Safety timer and current termination algorithms are supported for lithium chemistry batteries. The device also includes automatic recharge, pre-charge (Li-ion) and NTC thermistor protection. The I2C port of LTC4015 allows user customization of charger algorithms, reading of charger status information, programmable alerts, use and configuration of coulomb counter.
  • Digital telemetry system monitors VBAT, IBAT, RBAT, NTC ratio, VIN, IIN, VSYSTEM, die temperature
  • Integrated 14bit ADC
  • Wide charging input voltage range from 4.5V to 35V
  • Wide battery voltage range up to 35V
  • Input undervoltage charge current limit loop
  • Maximum power point tracking
  • Input and output ideal diodes provide low loss PowerPath operation
  • Input current limit prioritizes system load output
  • Instant-on operation with discharged battery
  • Operating junction temperature range from -40°C to 125°C
