IP places a charger for low-capacity batteries on SoC designs
The BC-Livingstone.01 can charge a single-cell battery from all types of USB adapters with a maximum current of 500 mA. This battery charger provides the final user with flexibility to choose the End-of-Charge. The IP offers 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 IP for Li-ion or Li-Po single-cell battery include:
– 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 three charge modes: trickle charge, constant current and constant voltage with fast charge with programmable current up to 500 mA
– Low power consumption: 50 µA in monitoring mode and 5 µA in shutdown mode
