Product Overview

The LTC3335EUDC#PBF is a nanopower high-efficiency buck-boost DC-to-DC Converter with an integrated precision coulomb counter which monitors accumulated battery discharge in long life battery-powered applications. The buck-boost can operate down to 1.8V on its input and provides eight pin-selectable output voltages with up to 50mA of output current. The coulomb counter stores the accumulated battery discharge in an internal register accessible via an I²C interface. The LTC3335 features a programmable discharge alarm threshold. When the threshold is reached, an interrupt is generated at the /IRQ pin. To accommodate a wide range of battery types and sizes, the peak input current can be selected from as low as 5mA to as high as 250mA and the full-scale coulomb counter has a programmable range of 32,768:1.
  • Integrated coulomb counter measures accumulated battery discharge
  • Programmable coulomb counter prescaler for wide range of battery sizes
  • Programmable discharge alarm threshold
  • Up to 90% efficiency
  • ±5% Battery discharge measurement accuracy
  • 680nA Low input quiescent current (output in regulation at no load)
