Texas Instruments announced Tuesday what it called the industry’s lowest termination current switching charger in an integrated circuit.
The new switching battery charger IC supports a termination current of 20 mA. That is well below the typical termination current of 60 mA of competing devices.
The IC, called the BQ25619, provides 7% higher battery capacity and longer run time, with ultra-fast charging. TI said the IC can double the shelf life of ready to use electronics, which includes small medical and personal electronics like hearing aids, earbuds and wireless charging cases, networked cameras, patient monitoring devices and more.
The IC integrates charging, boost conversion and voltage protection in one device, which should help designers in small applications. It eliminates the external inductor required by prior ICs. Only a single power device is required.
An evaluation module is available for $99. Pricing for the charger is $1.45 in 1,000-unit quantities. It comes in a 24-pin wafer quad flatpack. A 30-pin version will come later in 2019.
