  • Battery protection circuit and method for energy harvester circuit
    Patent number: 8253389
    Abstract: Power management circuitry (7-2,3,4) for converting a harvested voltage (Vhrv) to an output voltage (VBAT) applied to a battery (6) includes an inductor (L0) having a first terminal (3) coupled to receive the harvested voltage (Vhrv) and a second terminal coupled to a first terminal of a first switch (S0). The power management circuitry transfers the current generated by an energy harvester (2) to the battery if it (6) is not fully charged, and shunts the current away from the battery (6) to avoid overcharging if it is fully charged.
    Type: Grant
    Filed: February 17, 2010
    Date of Patent: August 28, 2012
    Assignee: Texas Instruments Incorporated
