Description

The STBC15 is a linear charger thin film battery with a maximum charging current

of 40 mA. The device uses a CC/CV algorithm to charge the battery. Thanks to the

ultra-low consumption architecture, the charger is suitable for low-capacity cells such

as thin film batteries and can use low energy sources such as energy harvesters. A 5

V input like a standard USB port can be used as a voltage source as well. A specific

version (-L) is available to charge Li-Ion cells.

The STBC15 integrates an over-discharge and overcurrent protection circuitry to

prevent the battery from being damaged under fault conditions. The floating voltage

value can be set to four different values by using dedicated selection inputs. A higher

set of floating voltages, suitable for Li-Ion batteries, is available in the -L version

of the product. A dedicated pin allows the device to be set in shelf-mode. In this

condition, the STBC15 consumes less than 10 nA, thus not discharging the battery

before the final device is activated by the end user. The ultra-low power architecture

allows the STBC15 to consume less than 250 nA when the input power source is

removed and less than 10 nA in over-discharge-mode.

The device is available in a (1.7 × 2.0 mm) 12-lead QFN package, 400 µm pitch, 0.55

mm max. thickness or in Flip-chip 1.1 x 1.4 mm 12 bumps 300 µm pitch.
