  • Electrostatic discharge protection circuit for implantable medical device
    Patent number: 9214799
    Abstract: An implantable medical device can include an integrated circuit comprising an electrostatic discharge (ESD) protection circuit. The ESD protection circuit can include an active circuit, a first passive circuit, and a second passive circuit. For example, at least one of the first or second passive circuits can include an array of capacitors in a series configuration, a parallel configuration, or a combination of series and parallel configurations. The first and second passive circuits can be configured to establish a specified time constant, and, in response to an applied ESD, the first and second passive circuits can provide a control signal to active circuit to switch the active circuit from a substantially non-conductive mode to a substantially conductive mode.
