  • 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.
