While a lot of small connected devices, such as wireless headsets, wearable devices, connected bracelets or smart watches, require low-power optimization. Dolphin Integration directly addresses low-capacity Li-Ion or Li-Po batteries with its new low-power battery charger. Indeed, the BC-Livingstone.01 can charge a single-cell battery from all kinds of USB adapters with a maximum current of 500 mA. This battery charger provides the final user with a high flexibility to choose the End-of-Charge.

The BC-Livingstone.01 benefits from advanced control and protection features, such as under/over voltage limitation or battery temperature monitoring, which bring all the safety expected in battery-powered applications.

To ease the SoC integration of the battery charger, the BC-Livingstone.01 is delivered with a set of simulation models for verifying the mode transitions.

Performance highlights of the BC-Livingstone.01 for Li-ion or Li-Po single-cell battery:

  • Input voltage up to 5.75 V enabled by design to cost-reduce by using standard CMOS 3.3 V/1.2 V logic process
  • Support of 3 charge modes: trickle charge, constant current and constant voltage with fast charge thanks to a programmable current up to 500 mA
  • Low power consumption: 50 µA in monitoring mode and 5 µA in shutdown mode

All Silicon IPs are designed by Dolphin Integration following ISO9001 quality procedures and are thoroughly verified through simulation using the single-kernel mixed-signal simulator SMASH™ by applying our rigorous Virtual Fab Process™ which ensures that measurements are guaranteed to qualify the silicon (as the VFP has ensured that simulation is predictive).
