Electrostatic discharge protection circuit for implantable medical device

摘要

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.
